β decay of ³⁶Mg and ³⁶Al: Identification of a β-decaying isomer in ³⁶Al

RADIOACTIVITY ³⁶Mg, ³⁶Al(β^-)[from ⁹Be(⁴⁸Ca, X), E=140 MeV/nucleon for experiment at NSCL and ⁹Be(⁴⁸Ca, X), E=172.3 MeV/nucleon for experiment at FRIB]; ³⁶Al, ^36mAl(β^-)[from ³⁶Mg(β^-); measured Eγ, Iγ; deduced T_1/2. ³⁶Al; deduced levels, J, π, newly-observed β-decaying isomer, T_1/2 of the isomer. ³⁶Si; deduced levels, J, π. Comparison to shell model calculations performed with the FSU interaction using code CoSMo. For experiment at NSCL - CeBr₃ based implantation detector with position-sensitive photomultiplier tube was surrounded by 16 segmented germanium detectors (SeGa) and 15 LaBr₃ detectors. For experiment at FRIB - YSO scintillator based implantation detector segmented into 48x48 pixels was surrounded by 11 HPGe clover detectors and LaBr₃ detectors from one side and the neutron detector array VANDLE from the other side.
