The nuclear structure of 158Tb

Although 158Tb has recently been of interest in a proposed method for a determination of the neutrino rest mass, there was considerable confusion about the nuclear structure of this nuclide. The present work describes several charged-particle reaction studies which have been performed to clarify the nature of the low-lying levels, and to search for previously unknown ones. Angular distributions of the 159Tb(d, t)158 and 161Dy(p, α)158Tb …
