Book Description
Inclusive electron scattering from nuclei at large x and Q^ is the result of a reaction mechanism that includes both quasi-elastic scattering from nucleons and deep inelastic scattering from the quark consitituents of the nucleons. Data in this regime can be used to study a wide variety of topics, including the extraction of nuclear momentum distributions, the influence of final state interactions and the approach to _v-scaling, the strength of nucleon-nucleon correlations, and the approach to x- scaling, to name a few. Selected results from the recent experiment E02-019 at the Thomas Jefferson National Accelerator Facility will be shown and their relevance discussed.

Book Description
This book provides an up-to-date, self-contained account of deep inelastic scattering in high-energy physics, intended for graduate students and physicists new to the subject. It covers the classic results which led to the quark-parton model of hadrons and the establishment of quantum chromodynamics as the theory of the strong nuclear force, in addition to new vistas in the subject opened up by the electron-proton collider HERA. The extraction of parton momentum distribution functions, a key input for physics at hadron colliders such as the Tevatron at Fermi Lab and the Large Hadron Collider at CERN, is described in detail. The challenges of the HERA data at 'low x' are described and possible explanations in terms of gluon dynamics and other models outlined. Other chapters cover: jet production at large momentum transfer and the determination of the strong coupling constant, electroweak interactions at very high momentum transfers, the extension of deep inelastic techniques to include hadronic probes, a summary of fully polarised inelastic scattering and the spin structure of the nucleon, and finally a brief account of methods in searching for signals 'beyond the standard model'.

Book Description
Electron Scattering from Complex Nuclei, Part B is a three-chapter text that explores the excitation of the nucleus to bound levels and the nucleus breakup through particle emission from continuum states. The first chapter discusses the inelastic scattering to nuclear levels, the giant resonances, the concepts of radiative corrections, and the phase shift analysis for inelastic scattering. The subsequent chapter concerns the quasi-elastic continuum and the observations of the nuclear decay products. The last chapter presents special topics on electron scattering, such as dispersion and exchange corrections, sum rules, and isospin effects. Physicists, researchers, and graduate students will find this book invaluable.

Book Description
The deep inelastic electron scattering cross sections per nucleon sigma/sub A/ for d, He, Be, C, Al, Ca, Fe, Ag, and Au were measured in the kinematic range 0.09 less than or equal to x less than or equal to 0.9 and 2 less than or equal to Q2 less than or equal to 15 (GEV/c)2 using electrons with energies ranging from 8 to 24.5 GeV. The ratio sigma/sub A//sigma/sub d/ is consistent with unity in the range 0.1

Book Description
Electron Scattering from Complex Nuclei, Part A covers the historical phases of experimental development in elastic and inelastic electron scattering. This five-chapter text presents the logical development of the underlying theory of electron scattering. After briefly discussing the history of electron scattering from nuclei, this book goes on describing the theory of elastic scattering from a point nucleus, both with Born approximation and the accurate solution of the Dirac equation, as well as the corresponding experiments. The following chapter considers the analysis of nuclear charge distributions experiments using Born cross section and phase-shift methods. A chapter is devoted to the complete elastic and inelastic Born theory. This chapter also deals with the derivation of a theorem on the general form of the electron-nucleus scattering cross section, with an emphasis on the influence of the neglected transverse interaction on the cross section. The last chapter presents the status of elastic scattering along with some topics in muonic atoms that also determine nuclear charge densities. This book will be of great benefit to physicists, researchers, and graduate students who are interested in nuclear structure problems.

Book Description
Quark constituents of nucleons were discovered in deep-inelastic electron scattering. It is not surprising therefore that the nuclear effects in deep-inelastic lepton scattering first observed by the European Muon Collaboration (EMC) have spawned many suggestions of revolutionary changes in our views of nuclear structure. Perhaps quarks play a far more active role in nuclear dynamics than the conventional theory provides. Before following the natural appeal of radical conclusions we believe it is important to examine in quantitative detail the consequences of the conventional nuclear model, in which the nucleon-nucleon potential features a one-pion exchange tail at large distances, an intermediate range attraction dominated by two-pion exchange and a strong short-range phenomenological repulsion. For this purpose let us assume that quarks are strictly confined to single hadrons, and that the quark structure of the hadrons in a nucleus is not affected by their environment. These assumptions allow a consistent description of deep-inelastic lepton-nucleus scattering, and the quantitative consequences agree well with available data. 15 refs.

Book Description
The workshop aimed to gather the electron scattering community to assess the present status of the experimental and theoretical research program at the electron scattering facilities that will be available in the near future. The topics discussed include nucleon form factors and deep inelastic structure functions, electro-production of nucleon resonances, final state interactions and nucleon-nucleon correlations in nuclei, electron-nucleon scattering with polarized beams and targets and nuclear transparency.
