摘要：
For the first time, two excited superdeformed (SD) bands have been observed in the double closed shell superdeformed nucleus Hg192. One of the SD bands exhibits a pronounced peak in the dynamic moment of inertia which is interpreted as a crossing between two excited SD configurations involving the N=7 intruder and the [512]5/2 orbitals. This is only the second occurrence of such a crossing in a SD nucleus around A=190. The second excited SD band has near identical transition energies to an excited SD band in Hg191. © 1995 The American Physical Society.
