beta -decay branching ratios of the neutron-rich nucleus 15B.

We have used the Michigan State University National Superconducting Cylcotron Laboratory A1200 radioactive beam facility and a newly designed neutron detector array to measure the first {beta}-delayed neutron spectrosopy of {sup 15}B and the {sup 15}B {beta}-decay branch to {sup 15}C bound states. The {sup 15}B ions were produced as projectile fragments in the interaction of an {ital E}/{ital A}=80 MeV {sup 18}O beam with a thick beryllium target. From these measurements, we deduce the {sup 15}B {beta}-decay branching ratios. The results are compared with shell-model predictions carried out in the {ital psd} model space.
