ASYMPTOTIC NORMALIZATION COEFFICIENTS FOR 27Al, 27Si MIRROR NUCLEI AND 28Si NUCLEUS FROM ANALYSIS OF ONE-NUCLEON TRANSFER REACTIONS

摘要

Differential cross sections for the one-nucleon transfer reactions 27Al(d,t)26Al, 27Al(3He, d)28Si, and 28Si(d, 3He)27Al at the incident particle energy of a few MeV were analyzed by the method combining the distorted-wave Born approximation and dispersion theory concepts. Vertex constants of single-particle coupling in the nuclei 27Al → 26Al + n and 28Si → 27Al + p were found. Values for the asymptotic coefficient of the bound state function were determined from the independent analysis of nuclear radii within the proton-neutron pair coupling model. Spectroscopic factors of the bound states 27Al → 26Al + n and 28Si → 27Al + p and vertex constants for the bound states 27Si → 26Al + p and 28Si → 27Si +n were obtained with those values.
