On the interpretation of photonuclear angular distributions

摘要: Abstract Photonucleon angular distributions are calculated in the j − coupling scheme for single-particle excitations. The electromagnetic interaction of nucleus with photon beam is treated electric dipole and quadrupole absorption approximations. general results allow extraction information about one-particle-one-hole transition strengths from experimentally-measured distributions. importance coherent interference terms cross section discussed. It shown that, except special cases, amount involved photoproton production can be estimated only to nearest order magnitude asymmetry 90° distribution. effects inclusion spin-orbit force on interpretation by Shoda systematics 1d-2s shell nuclei described briefly.
