MICROSTRUCTURE MANIFESTATIONS IN NUCLEAR REACTIONS

摘要

Photonuclear reaction yields were studies at the range of giant dipole resonance for medium-mass targets and the probabilities for population of different final states were deduced and analyzed. In addition to the expected statistical trends expressed in the influence of the reaction threshold and of the product spin, there are observed the microstructure manifestations due to the individual level schemes of the products. The internal status of nucleons and their single-particle orbital momentum also make influence onto the reaction yield. The effects are isolated on the scale from tens % to orders of magnitude for the probability and branching ratio in reactions at modest energy.
