Book Description
Photoproduction of pions from complex nuclei has become an investigative tool for (1) the detailed form of the elementary photopion amplitude, (2) the pion-nucleus optical potential, (3) nuclear structure, and (4) off-shell and medium effects on the elementary amplitude in nuclear processes. In this book, all these aspects are considered in detail. With improved experimental accuracy and beam tech- nology the study of nuclear pion photoproduction will break new ground and become an even more powerful investigative tool. This monograph is intended as an introductory guide as well as a reference manual for grad- uate students and researchers working in this important area of physics.

Book Description
The proceedings reflect the recent experimental and theoretical progress in pion nuclear physics in topics like pionic atoms, pion absorption, charge exchange, (π, 2π), and others involving pions in nuclei using different probes, as electron photons or heavy ions. Related topics on chiral symmetry, low energy πN and (γ, π⁰) and quark degrees of freedom are also addressed.

Book Description
The photoproduction of neutral pions from complex nuclei is expressed in terms of the photoproduction from single nucleons by means of the direct interaction model and the impulse approximation. A summation over all final states of the nucleus is performed by means of a closure approximation.

Book Description
Excerpt from Threshold Photo and Electroproduction of Pions From Nuclei To find the amplitude from a single nucleon, one usually starts by considering which relativistic Feynman diagrams are important in the particular energy region under consideration. For the case of a purely electromagnetic interaction as in electron scattering, photo or electro disintegration, or Compton scattering, one can use perturbation theory and quantum field theory to give the appropriate Feynman diagrams to a particular order in the coupling constant. However, in photo or electro production of pions, we now have electromagnetic and strong interactions, and since the coupling constant in strong interactions is large, the perturbation expansion in powers of the coupling constant will not con verge. In spite of this fact, the lowest order term in the expansion using pseudovector pion-nuclear coupling, gives results which under cer tain conditions agree very well with experiment and with the low energy theorem derived from the theory of the pcac (partially conserved axial current) Therefore, we will use the lowest order perturbation term as our model for the threshold photo pion production amplitude off of a nucleon.
