Levels in {sup 190}Hg were studied by radioactive decay of isotopically separated {sup 190}Tl. A new band was observed with spin parity (energy, keV) of 0{sup +}(1279), 2{sup +}(1571), 4{sup +}(1975), and 6{sup +}(2510). Electric monopole transitions were observed between this band and the ground-state band. Relative {ital B}({ital E}2) values for intraband transitions in the new band were found to be {similar to}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.
