Book Description
Since the mid-1980s increasing effort has been put into light exotic nuclei, that is light nuclei of unusual composition. The research of the exotic nuclei began with the advent of accelerated beams of such nuclei. This new technique has revitalized nuclear physics, and the facilities producing radioactive ion beams now offer opportunities for pion

Book Description
This book presents an overview of the different few-body techniques developed in nuclear physics and their applications to explore the structural properties of neutron-rich unstable nuclei, the so-called halo nuclei. Formal theory of two- and three-body scattering are discussed in a compact and abridged form to initiate the beginners who want to investigate the problems of halo nuclei within the framework of three-body models. Readers gain in-depth knowledge about the methods involved to solve the two- and three-body scattering problem and a special focus is put on the Faddeev approach. In this sense, the authors address both the graduate students and senior researchers. Subsequently, a detailed analysis of the Efimov effect in three-body systems is presented and the search for the effect in atomic nuclei, both Borromean and non-Borromean is addressed. The book also presents a detailed account of how to analyze, within the framework of a 3-body approach and using realistic short range forces, the structural properties of halo nuclei. Finally, the authors discuss the recent progress in effective field theory by setting up the integral equations for 3-body scattering and applying it to study low energy scattering of neutrons off halo nuclear targets.

Book Description
The monograph describes the properties of the lightest nuclei with large excess of neutrons. The results of theoretical and experimental studies of neutron-rich isotopes with 1 ≤ Z ≤ 20 are presented while also changes in the structure of nuclei when going away from the line of β-stability are discussed. Information presented is on the mass, radii of distribution of nuclear matter, energy levels for excited states of these nuclei, the possibility of manifestation of a halo, as well as the deformation of nuclei and the quantum properties of ground states. The position of the boundary of nucleon stability for these nuclei is considered. The effects associated with weakening and even the disappearing influence of standard magic numbers and the appearance of new ones are discussed.The results presented in the book will be useful in other fields of science as well, including astrophysics.

Book Description
While neutron halos were discovered 30 years ago, this is the first book written on the subject of this exotic form of nuclei that typically contain many more neutrons than stable isotopes of those elements. It provides an introductory description of the halo and outlines the discovery and evidence for its existence. It also discusses different theoretical models of the halo's structure as well as models and techniques in reaction theory that have allowed us to study the halo. This is written at a level accessible to graduate students starting a PhD in nuclear physics. Halo nuclei are an exotic form of atomic nuclei that contain typically many more neutrons than stable isotopes of those elements. To give you a famous example, an atom of the element lithium has three electrons orbiting a nucleus with three protons and, usually, either 3 or 4 neutrons. The difference in the number of neutrons gives us two different isotopes of lithium, Li6 and Li7. But if you keep adding neutrons to the nucleus you will eventually reach Li11, with still 3 protons (that means it's lithium) but with 8 neutrons. This nucleus is so neutron-rich that the last two are very weakly bound to the rest of the nucleus (a Li9 core). What happens is a quantum mechanical effect: the two outer neutrons float around beyond the rest of the nuclear core at a distance that is beyond the range of the force that is holding them to the core. This is utterly counterintuitive. It means the nucleus looks like a core plus extended diffuse cloud of neutron probability: the halo. The author of the book, Jim Al-Khalili, is a theoretician who published some of the key papers on the structure of the halo in the mid and late 90s and was the first to determine its true size. This monograph is based on review articles he has written on the mathematical models used to determine the halo structure and the reactions used to model that structure.

Book Description
Few-body resonances are in the frontiers of resonance studies. Very similar problems occur in atomic and molecular physics, nuclear physics and high-energy physics. This collection presents the state of the art of the studies of resonance states in these fields and demonstrates their common methodological aspects. Most of the contributions are theoretical, but quite a few are closely linked with experiments through the data they are dealing with.

Book Description
The ENAM2001 Conference was held on July 2-7, 2001 at the Rantasipi Aulanko Hotel in Hameenlinna in southern Finland. The conference was organized by the Department of Physics and the Accelerator Laboratory of the University of Jyvaskyla with support from the Physics Departments of the Universities of Helsinki and Turku. This conference, Exotic Nuclei and Atomic Masses has now gained the status of a major nuclear physics serial conference. The previous conference was held in Bellaire, Michigan, USA. The conference was first held in 1967 in Lysekil, Sweden, then entitled Conference on Nuclei Far from Stability. ENAM2001 welcomed 270 participants from 34 countries, including 17 accompanying per sons. The content of the program was selected based on the advice of the International Advisory Committee. The Committee members read and considered 253 submitted abstracts in selecting oral contributions. During the conference week 76 invited and oral talks were given. The rest of the contributions were presented in dedicated poster sessions. Many thanks go to the speakers of oral and poster presentations for their enthusiasm and for the high quality of their work which demonstrated the liveliness of the field. Participation in the lectures was high and contributions from the audience were important towards the success of this conference. The organizers would like to especially thank Cary Davids of Argonne National Laboratory for his comprehensive summary talk, which is also included in these Proceedings.

Book Description
This book is a collection of talks presented at the First International African Symposium on Exotic Nuclei (IASEN-2013). The symposium was held at Cape Town, South Africa from 2 - 6 December 2013. The IASEN2013 was dedicated to the problems of producing and investigating nuclei far from the line of stability. The symposium was organized by two scientific centers: iThemba LABS, South Africa and the Joint Institute for Nuclear Research (Dubna).The main goal of the Symposium was to discuss the latest results on the production and study of the properties of the lightest to heaviest nuclei, as well as the plans for future joint investigations in the field of exotic nuclei. The talks were presented by the leading scientists in the field. Among the topics of the symposium were the following: production and study of properties of nuclei in extreme states, strongly deformed nuclei, highly excited and nuclei far from the line of stability as well as nuclei having large angular momenta. New results of the investigations are presented in this book. In particular, the latest results on the synthesis of new superheavy elements are also presented. At the Symposium were talks devoted to existing detecting devices and accelerators of exotic nuclei as well as to the future projects for the creation of similar set-ups.
