Low-lying excitations in ⁷²Ni

RADIOACTIVITY ⁷²Co(β^-), (β^-n), (β^-2n), ⁷³Co(β^-n)[from ⁹Be(²³⁸U, F), E=345 MeV/nucleon using BigRIPS separator and ZeroDegree spectrometer at RIBF-RIKEN facility]; measured Eγ, Iγ, βγγ-coin, (⁷²Co implants)β-correlations, half-lives of low-spin and high-spin activities of ⁷²Co using WAS3ABi setup and EURICA array, level half-lives by fast-timing γγ(t) method. ⁷²Ni; levels, J, π, β feedings, logft values, configurations. ^70,71Ni; observed γ rays from β-delayed-neutron decay of ⁷²Co. Comparison with previous experimental results, and with simple shell-model calculations including only neutron excitations across the fpg shells.
