Description

A new transition is reported in the beta-delayed neutron decay of 18N. The observed neutron energy is 3.78±0.05 MeV with a branching ratio of 0.05±0.03%, which corresponds to an excitation energy of 12.05±0.05 MeV in the daughter nucleus 18O. The log ft value of this transition is 5.24±0.3, which, together with the previously reported electron scattering data, determines the Jπ value of this level to be 1-. The experimental data are compared to the shell model calculations in different model spaces
