Excited states in the Tz=−1 nucleus 70 Kr have been populated using inelastic scattering of 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 42+ state suggest shape coexistence in 70 Kr.< Réduire
