Abstract：
Anomalous behavior of the dynamic moments of inertia is interpreted for the two SD bands (¹⁹³Hg(b1) and ¹⁹³Hg(b4)) in the A ~190 region in terms of a parametrized two-band mixing model. The calculations predict that the dynamic moments of inertia J⁽²⁾ will start to decrease at about hw ≈ 0.42 MeV for ¹⁹⁴Hg(b1).
