| Resumo: | Nuclear technology developments and nuclear astrophysics studies impose high data requirements on neutron-rich nuclei in terms of amount and quality. Radioactive decay data on -delayed neutron emitters are of particular relevance given the important role delayed neutrons play in both fields. In 2013, the International Atomic Energy Agency (IAEA) started Coordinated Research Project (CRP) on a reference database for beta-delayed neutron emission evaluation [170]. The database, which is in the process of publication [168], includes -delayed neutron emission probabilities for 309 nuclei, about a hundred more than Evaluated Nuclear Structure Data File (ENSDF) to date (as of July, 2020) [7,8]. But there is a long road ahead to meet the delayed neutron data requirements of nowadays nuclear science and technology. The recent large-scale theoretical evaluation by Marketinet al. [6] on 5409 neutron-rich nuclei predicts that 90% of them are -delayed neutron emitters... |
