The structure of semi-magic 70 28 Ni 42 was investigated following complementary multinucleontransfer and secondary fragmentation reactions. Changes to the higher-spin, presumed negativeparity states based on observed γ-ray coincidence relationships result in better agreement with shell-model calculations using effective interactions in the neutron f 5/2 pg 9/2 model space. The second 2 + and (4 + ) states, however, can only be successfully described when proton excitations across the Z = 28 shell gap are included. Monte-Carlo shell-model calculations suggest that the latter two states are part of a prolate-deformed intruder sequence, establishing an instance of shape coexistence at low excitation energies similar to that observed recently in neighboring 68 Ni.

“…The manifestation of shape coexistence in atomic nuclei is a unique phenomenon strongly related to shell gaps and the residual proton-neutron interaction, leading to particle-hole excitations and deformation [1]. Evidence for this can be found all over the nuclear chart in regions close to shell-or subshell closures.…”

The low-energy structure of the neutron-rich nucleus 68 Ni has been investigated by measuring the β decay of the low-spin isomer in 68 Co selectively produced in the decay chain of 68 Mn. A revised level scheme has been built based on the clear identification of β-γ -E0 delayed coincidences. Transitions between the three lowest-lying 0 + and 2 + states are discussed on the basis of measured intensities or their upper limits for unobserved branches and state-of-the-art shell model calculations.

“…As a function of nucleon number, many nuclei in this region evolve through a range of collectivity and nuclear shapes, including nearly spherical, prolate, and oblate, and with varying degrees of triaxiality. In addition, multiple shapes may coexist within the same nucleus, with different configurations competing to become the yrast configuration [2].…”

The lifetimes of the yrast 8 + and 9 + states of 70 As have been measured via the γ-ray lineshape method following population by the 9 Be( 78 Rb, 70 As) reaction at 101.6 MeV/nucleon. The strength of the E1 8 + → 7 − transition is found to be B(E1) = 1.3(5) × 10 −5 e 2 fm 2 or 1.2(4) × 10 −5 Weisskopf units (W.u.) while the 9 + → 8 + M1 transition is found to have a strength of B(M 1) = 1.5(8) µ 2 N or 0.85(42) W.u. The implications for the structure of these states is discussed and found to be consistent with an assignment to a πg 9/2 νg 9/2 configuration.
