Abstract

The β-delayed neutron emission of ¹⁹C has been studied with the hope of observing states in ¹⁹N close enough to the ¹⁸N+n threshold to be of astrophysical significance. Although transitions to three-neutron unbound states in ¹⁹N have been observed, no states in the energy region of astrophysical relevance were found. The ¹⁹C β-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.
