Excited states in $^{217}$Ra populated in the α decay of $^{221}$Th

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 $E_{\alpha} \mathrm{(keV)} [b_{\alpha}(\%)]=7951(8)[0.14(3)]$ and $8247(3)[1.51(12)]$, to...
