Beta decay of /sup 30/Na: Experiment and theory

Journal Article · · Phys. Rev. C; (United States)
The /sup 30/Na ..beta.. decay was studied on-line by means of mass-separation techniques. Gamma-ray, gamma-gamma, neutron-gamma spectra, neutron time-of-flight singles, and ..gamma..-coincidence measurements were registered. High-energy neutron branches (E/sub n/>2 MeV) were found complementing previously reported data. A /sup 30/Na ..beta..-decay scheme to /sup 30/Mg bound and unbound states is established. The distribution of the transition strength as a function of the excitation energy for particle-unbound levels in /sup 30/Mg is compared to shell-model calculations performed in the 0--12 MeV excitation energy range. An overall renormalization yields a B(GT) quenching factor of 0.28 substantially lower than generally observed in this mass region. Three levels in /sup 29/Mg which are strongly populated via the 1n channel are related to negative-parity intruder states.
