Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Neutral pion photoproduction on the nucleon near threshold is investigated using a dynamical model. It is shown that the commonly used procedure, based on an analytical continuation of the K-matrix to the unphysical region, is not compatible to a dynamical approach. We show that the final state interaction (FSI) amplitude derived from a dynamical model could involve large cancellation between the different pion photoproduction mechanisms. This leads that the FSI due to the intermediate [pi]°p state can be as important as that due to the [pi]n intermediate state. At threshold, we obtain E{sub 0+} = -1.92 × 10−3/m{sub {pi}+}. This number is close to the measured value of E{sub 0+} = -1.5 × 10−3/m{sub {pi}+}. No violation of the low energy theorem is required to obtain good agreement between the calculated total cross sections and experimental data drum threshold to about 400 MeV incident photon energy. 10 refs., 4 figs., 3 tabs.

This book was released on 1966 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: In a previous experiment the cross section for the photoproduction of pions in hydrogen near the second pion nucleon resonance was measured at 135 degrees and 180 degrees in the CMS. At 180 degrees the measurements did show a very sharp peak at a gamma ray energy of 700 MeV. The experiment has now been repeated only at 180 degrees, with improved energy resolution. The new results, in agreement with the old ones, show the same sharp energy dependence at about the same value of the primary energy. (Author).

This book was released on 2017-11-19 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: NSA is a comprehensive collection of international nuclear science and technology literature for the period 1948 through 1976, pre-dating the prestigious INIS database, which began in 1970. NSA existed as a printed product (Volumes 1-33) initially, created by DOE's predecessor, the U.S. Atomic Energy Commission (AEC). NSA includes citations to scientific and technical reports from the AEC, the U.S. Energy Research and Development Administration and its contractors, plus other agencies and international organizations, universities, and industrial and research organizations. References to books, conference proceedings, papers, patents, dissertations, engineering drawings, and journal articles from worldwide sources are also included.
