15N (α, p) 18O Reaction]]>

摘要

The differential cross section for the ( α, p )_(18)O reaction at an α-particle energy of 30 MeV is analyzed in the context of direct reaction mechanisms and the compound nucleus model. Spectroscopic amplitudes are calculated at the vertices of the diagrams illustrating triton and_(14)С cluster transfer reactions, including cases of mixed configurations of 1 p –2 d shells. The OP parameters of α–_(15)N and p –_(18)O interaction are found that provide the best agreement between the calculated and experimental data at an energy of ~30 MeV. It is shown that the main contribution to the production of protons comes from direct triton cluster transfer. The role of the heavy_(14)С cluster transfer mechanism and the compound nucleus mechanism is notable in the region of angles greater than 90°.
