First half-life measurement of a low-lying isomer in ³⁷Si

RADIOACTIVITY ^37,38Al(β^-), (β^-n)[from ⁴⁸Ca(⁹Be, X), E=140 MeV/nucleon]; measured Eγ, Iγ, Iβ, γγ-coin, βγ-coin; deduced T_1/2. ³⁷Si; deduced levels, J, π, T_1/2 of isomeric states at 68- and 156-keV, B(M1), matrix elements for low-lying ground-state M1 transitions. ^36,38Si; deduced Eγ, Iγ, transition intensities. Comparison to other experimental data and shell model calculations using the SDPF-MU, SDPF-U-SI, and FSU interactions. CeBr₃ based implantation detector with position-sensitive photomultiplier tube surrounded by 16 segmented Ge detectors (SeGa) and 15 LaBr₃ detectors at Coupled Cyclotron Facility (NSCL, MSU).
