| Abstract: | Theγ decay in the radiative fusion reaction90Zr+90Zr→180Hg+xγ has been observed in an array of NaI detectors. States up to 6+ in the yrast sequence of180Hg are tentatively assigned and suggest the coexistence of weakly oblate and strongly prolate nuclear shapes. The difference in potential energy between the two inferred shapes has dropped to about 200 keV, continuing the downward trend observed in the heavier even isotopes188–182Hg. |
