Abstract

Levels in

{}^{190}{Hg}

were studied by radioactive decay of isotopically separated

{}^{190}{Tl}

. 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.
