“…In the present work, αγ -coincidence analysis has been used to establish the energies of the two excited states reported in Refs. [5,6] [38,39] for 213 Po, [33,40,41] for 215 Rn, [13,33] for 217 Ra, and [42,43] for 219 Th. Hindrance factors of α decays from parent nuclear states, indicated on the upper x axis, to the product states are shown in brackets from Refs.…”

Fine structure in the α decay of 221 90 Th, populating excited states in 217 88 Ra, was studied using αγ -coincidence spectroscopy. Two α-decay branches from 221 Th have been newly observed, with E α (keV)[b α (%)] = 7951(8)[0.14(3)] and 8247(3)[1.51( 12)], together with three previously known branches. Also, two new states in 217 Ra were identified at E = 177 and 227 keV. The ground-state configurations of the odd-A, N = 131 transitional isotones above 208 Pb are interpreted from their α-decay fine structure systematics and considered in terms of predictions using spherical shell and reflection-asymmetric models.
