  A study of the photo-disintegration of the deuteron using a cloud chamber as a detector has been made for gamma-ray energies of and Mev from the F(p,α)O 16* reaction. By observing the number of photo-disintegration protons and the number of electron pairs formed in the gas (CD 4) of the cloud chamber, the ratio of the photo-disintegration cross section to the pair cross Cited by: 8. Almost at the same time, in , the first theoretical paper on the photodisinte­ gration of the deuteron entitled "Quantum theory of the diplon" by Bethe and Peierls (BeP 35) appeared. It is not without significance that these two papers mark the be­ ginning of photonuclear physics in general and emphasize in particular the special role the two-body system has played in nuclear physics since then . Exclusive deuteron photo-disintegration (d! pn) is an excellent laboratory for studying this transition. The use of real photons increases the momentum transferred to the detected nucleon 4-fold over its companion exclusive process, elastic electron-deuteron scattering [1]. THE photodisintegration of the deuteron into a proton and a neutron is a case of the two-body problem in nuclear physics; the effect was first discovered by Chadwick and Goldhaber 1.

Abstract Recent experiments on n-p radiative capture at thermal energies, including the study of double-photon decay, and on the photo-disintegration of the deuteron are discussed. Comparisons between the results and contemporary theories are made whenever they are meaningful. Suggestions for some necessary experiments for the future are made. Photodisintegration (also called phototransmutation) is a nuclear process in which an atomic nucleus absorbs a high-energy gamma ray, enters an excited state, and immediately decays by emitting a subatomic incoming gamma ray effectively knocks one or more neutrons, protons, or an alpha particle out of the nucleus. The reactions are called (γ,n), (γ,p), and (γ,α). Deuteron photodisintegration in the medium energy range by R. M. K. HaМ€maМ€laМ€inen.

Part-2 explores the two-nucleon potential through the study of the deuteron problem, nucleon-nucleon scattering, and also presents a meson theoretical description of the nuclear potential. Part-3 deals with the nuclear structure through different models, e.g., liquid-drop model, Fermi gas model, nuclear shell model, collective model.   Introduction The deuteron is the most fundamental nuclear laboratory and for this reason, deuteron photo-disintegration d('~, np) has been extensively studied for the last sixty years [ 1 ]. l Present Address: ISN, Avenue des Mart F Grenoble Cedex, France. /98/$ (g) Published by Elsevier Science B.V.   In nuclear physics, they include the first calculations (with Bethe) on the photo-disintegration of the deuteron (made in response to a challenge by Chadwick), the Kapur-Peierls theory of .   deuteron photo-disintegration Low energies There are several nice advances in low-energy deuteron photodisintegration from the past several years. Polarization measurements from TUNL demonstrate that photodis- integration at energies of a few MeV, in an energy region appropriate for understanding baryosynthesis, is well predicted in both.
