β^- decay of neutron-rich ⁴⁵Cl located at the magic number N=28

RADIOACTIVITY ⁴⁵Cl(β^-), (β^-n)[from Be(⁴⁸Ca, X), E=140 MeV/nucleon]; measured Eγ, Iγ, Eβ, Iβ, βγ-coin; deduced T_1/2, Q values, β-feedings, branchings; calculated logft. ^44,45Ar; deduced levels, J, π. Comparison to shell-model calculations with FSU interaction. Systematics of the first excited 2⁺ state energy for the even-A Ar isotopes (from N= 20 to 30). Beta Counting System (BCS) equipped with a 986 υm thick pixelated (40 strips x 40 strips) DSSD detector, followed by SSCD and surrounded by 16 Clover detectors at NSCL.

NUCLEAR STRUCTURE ^43,44,45Ar; calculated levels, J, π, B(M1), B(E2), proton and neutron occupation numbers. Shell-model calculations with FSU interaction. Comparison to experimental data.
