Beta-delayed neutron spectroscopy of $^{24}O$.

ORAL

Abstract

Neutron spectroscopy is an important tool to probe the nuclear structure effects of neutron-rich nuclei, where beta-delayed neutron emission is a dominant decay mode. Beta-decay of parent nuclei populates neutron unbound states in the daughter nuclei which de-excite via neutron emission. Measuring neutron energy provides information about the excited states in the emitter which is otherwise not accessible through normal beta-decay measurement. The neutron energy spectrum measurement of the beta-delayed neutron precursor $^{24}O$ was performed for the first time at National Superconducting Cyclotron Laboratory (NSCL) using two different neutron detector arrays: NEXT and VANDLE. NEXT is a newly developed high-resolution segmented neutron time-of-flight array with neutron interaction position localization and neutron-gamma discrimination capabilities that enable precise energy measurement. The result from beta-delayed neutron emission measurement for $^{24}O$ will be presented.
