Probing isospin symmetry in the (⁵⁰Fe, ⁵⁰Mn, ⁵⁰Cr) isobaric triplet via electromagnetic transition rates

NUCLEAR REACTIONS ⁴⁰Ca(¹²C, pn), (¹²C, 2p), E=30-36 MeV; measured Eγ, Iγ, γγ-coin, level half-lives by recoil distance Doppler-shift (RDDS) technique using an array of 11 HPGe detectors, and Cologne plunger device at the University of Cologne. ⁵⁰Mn, ⁵⁰Cr; deduced levels, J, π, E2 matrix elements, B(E2) values for T=1 isobar analog states in ⁵⁰Fe, ⁵⁰Mn, and ⁵⁰Cr. Comparison with shell model calculations using the GXPF1A and KB3GR interactions, and with previous experimental results. ⁵⁰Fe; pointed out need for a more precise value of B(E2) for the first 2+ state.
