Abstract

Levels in Hg190 were studied by radioactive decay of isotopically separated Tl190. A new band was observed with spin parity (energy, keV) of 0+(1279), 2+(1571), 4+(1975), and 6+(2510). Electric monopole transitions were observed between this band and the ground-state band. Relative B(E2) values for intraband transitions in the new band were found to be 200 times those for interband transitions. Systematics of shape coexistence in the light Hg isotopes and their possible relevance to recent observations of superdeformation in these nuclei are discussed. © 1991 The American Physical Society.
