Abstract
An excited superdeformed (SD) band in Hg-190 has been observed to decay directly to the superdeformed yrast states. On the basis of its unusual properties, it has been proposed to be an octupole vibrational band. In this work we have firmly established the octupole vibrational character by measuring the electromagnetic nature of the transitions linking the excited to the yrast SD states.
