Beta-delayed neutron emission studies of neutron-rich Sc isotopes with FRIB Decay Station initiator.*

As the beta decay Q-value increases and the neutron separation energy in the daughter nucleus decreases for neutron-rich nuclei, beta-delayed neutron emission becomes a predominant decay mode. Measuring neutron energy is crucial for studying beta decay to neutron unbound states. This presentation focuses on the first beta-delayed neutron spectroscopy of neutron-rich Sc isotopes using the FRIB Decay Station Initiator (FDSi). Utilizing a high-resolution neutron time-of-flight array (NEXTi) in conjunction with a gamma-ray detector array (DEGAi), we studied beta decay to both neutron-bound and unbound states in Ti isotopes. Preliminary results on the neutron branching ratio measurements of Sc isotopes and the beta decay strength distribution in Ti isotopes will be presented.
