Abstract
The 152Gd(t, p) 154Gd reaction has been studied using 15 MeV tritons from the McMaster University tandem accelerator facility. The reaction products were analyzed with a magnetic spectrograph. Distinctive L = 0 angular distributions indicated that four 0 + states were populated, the first three with comparable strengths and the fourth with a cross section about an order of magnitude smaller. The 2 + 3 state at 1418 keV, previously interpreted as the 2 + member of the two-phonon beta-vibrational band, has been populated as strongly as the 2 + member of the ground-state band. The 0 + 3 and 2 + 3 states in 154Gd are analogous to the previously observed “spherical” states coexisting in the “deformed” 152Sm isotone.
