Nuclear structure research. Annual progress report
The most significant development this year has been the successful elucidation of the low-energy systematics of the very neutron-deficient Pr, Nd, Pm, and Sm isotopes. This includes an extensive set of Nilsson bandheads in {sup 133}Nd. Some serious errors in earlier decay scheme work were found. The results require some significant reassessments of mean-field calculations in this region. Part of our program continues to focus on shape coexistence and electric monopole (E0) transitions in nuclei. Following the discovery of coexisting ``gamma`` bands connected by E0 transitions in {sup 184}Pt, a similar behavior in {sup 186}Pt was established from {sup 186}Au decay data. This includes a pure E0 transition between states with J{sup {pi}} = 3{sup +}, just as was seen in {sup 184}Pt. Progress has been made in elucidating the low-energy systematics of the neutron-deficient Ir isotopes. A search for the population of the superdeformed band in {sup 194}Pb in the decay of {sup 194}Bi was unsuccessful. An extensive program of systematics for nuclei at and near N = Z has been initiated.
