Abstract
The lifetime of the lowest , T=1 state of , which decays 100% to a lower , T=0 state, has been measured by the recoil-into-plunger Doppler method. The result, τ=29.3±1.0 ps, gives the average τ=28.3±0.8 ps when combined with an earlier result. A comparison of the B(M1) extracted from this lifetime with the Gamow-Teller strength for the analog β decay from the ground state of to the same , T=0 state in shows that the orbital part of the M1 γ transition is greatly enhanced relative to the spin part. These results are interpreted in the context of realistic shell-model calculations for sd-shell nuclei.
