Abstract
It has been known from some time that the intrinsic state labeled by the asymptotic quantum numbers [631] lies quite close (<0.1 keV) to the [633] ground state of . Using the energies of selected γ rays emitted following the α decay of , we have obtained a value of 1±4 eV for the energy separation of these two intrinsic states.
