Abstract
The β-decay of odd-A, neutron-rich and are studied. More precise β-decay half-lives of and ms are deduced for and , respectively. In addition, β-delayed γ-ray spectroscopy is used to deduce β-decay branching ratios and establish the low-energy-level structures of the daughter nuclides. The new data for levels in and are compared with the results of shell-model calculations completed in the full pf model space. Both and show evidence of modest oblate deformation near the ground state.
