Shape coexistence and isospin symmetry in A = 70 nuclei: Spectroscopy of the Tz = −1 nucleus 70Kr
2018
Abstract Excited states in the T z = − 1 nucleus 70 Kr have been populated using
inelastic scatteringof a radioactive 70 Kr beam as well as one- and two-neutron removal reactions from 71,72 Kr at intermediate beam energies. The level scheme of 70 Kr was constructed from the observed γ -ray transitions and coincidences. Tentative spin and parity assignments were made based on comparison with the mirror nucleus 70 Se. A second 2 + state and a candidate for the corresponding 4 2 + state suggest shape coexistence in 70 Kr.
