Beta decay of exotic TZ = −1 and TZ = −2 nuclei

The half-lives of the TZ = −2, 56Zn and TZ = −1, 58Zn isotopes and other nuclei were measured in a β-decay experiment at GANIL. The energy levels populated by the 56Zn β decay were determined. The 56Zn results are compared with the results of the mirror process, the charge exchange reaction 56Fe(3He,t)56Co.
