摘要：
A method for describing the direct nucleonic decay of single-particle quasistationary states of near-magic nuclei is proposed and applied to some specific examples. The method is based on the optical model generalized to take into account channel coupling. The relative intensities of the decay of some single-particle quasistationary states of the Zr-91, Pb-209 Nb-91, and Bi-209 nuclei to the ground state and some low-lying (single-phonon) states of the product Zr-90 and Pb-208 nuclei are calculated by using the optical-potential parameters determined from analysis of nucleon-nucleus scattering. The results of the calculations for neutronic decay are compared with corresponding experimental data obtained from analysis of cross sections for one-nucleon-transfer reactions.
