Delayed neutron emission near the shell-closures

The self-consistent Density Functional + Continuum Quasi-particle Random Phase Approximation approach (DF+CQRPA) provides a good description of the recent experimental beta-decay half-lives and delayed neutron emission branchings for the nuclei approaching to (and beyond) the neutron closed shells N = 28, 50, 82. Predictions of beta-decay properties are more reliable than the ones of standard global approaches traditionally used for the r-process modelling. An impact of the quasi-particle phonon coupling on the delayed multi-neutron emission rates P_2n, P_3n,... near the closed shells is also discussed. (authors)
