摘要：

The beta-delayed neutron emission of C-19 has been studied with the hope of observing states in N-19 close enough to the N-18+n threshold to be of astrophysical significance. Although transitions to three-neutron unbound states in N-19 have been observed, no states in the energy region of astrophysical relevance were found. The C-19 beta-decay branching ratios to the observed states have been measured. All states show log(ft) values typical of allowed transitions. The results are compared with shell-model predictions carried out in the psd model space.
