AbstractAbstract
[en] In the very neutron-rich nuclei, the beta-decay occurs with some accompanying processes as neutron emissions. The beta-delayed fission also takes place in the superheavy nuclear mass region. The beta-decayed neutron process is an important phenomenon for manipulating nuclear reactor, and the beta-delayed fission critically affects the termination of the r-process nucleosynthesis in stars. We performed a systematical calculation of probabilities of beta-delayed neutron and beta-delayed fission in the entire region of nuclear chart with the improved gross theory of beta-decay and the KTUY mass model.
