摘要：

High-precision Lifetime measurements have been performed in two of the superdeformed (SD) bands of Hg-190 with the Doppler-shift attenuation method. Intrinsic quadrupole moments, Q(0), were extracted for the yrast and first excited SD bands in this nucleus. Dipole transition rates have been established for the inter-band transitions which connect the first excited SD band to the yrast states in the second minimum. The results support the interpretation of the excited SD band as a band based on an octupole vibration. Published by Elsevier Science B.V.
