     7.52(1/2+)   Decay mode is not known; however, one can assume a conservative estimate of log ft|>5 for any β branch to a level in 121In. For a branch of 1% to the 313 level for example, one gets T1/2(parent)>0.1s, leading to B(M1)(W.u.)<4×10-9 or B(E2)(W.u.)<7×10-5. These are both unreasonably small. Any larger β branching would give even smaller Weisskopf estimates, as would 1% branches to higher lying levels. Any possible β branching must thus be <<1%.
