Abstract

Discrete γ rays directly connecting states of a superdeformed (SD) band in 194Hg to the yrast states have been discovered. Thus, the excitation energies and spins of all members of the lowest SD band are established for the first time, together with their likely parity. The SD band decays from its 10+ and 12+ states, which lie 4204.8 and 4407.4 keV above the normal-deformed yrast states of the same spins.
