The decays of ⁷⁰,⁷²Ga to levels of ⁷⁰,⁷²Ge and the neutron capture cross sections of ⁶⁹,⁷¹Ga.
The decays of 21-min (70)Ga and 14-h (72)Ga have been studied from neutron-irradiated Ga. Several discrepancies in previous studies are resolved and inconsistencies in the previous (72)Ge data set are addressed. New values are proposed for the energies and β-decay branchings of the (72)Ge levels. Energies and intensities of the (70)Ga γ rays are also discussed. A new measurement and critical discussion of the (72)Ga half-life is offered. Measurements of the (69)Ga and (71)Ga thermal neutron capture cross sections and resonance integrals are also reported.
