Title: Longitudinal Wobbling Motion in {sup 187}Au

Abstract

The rare phenomenon of nuclear wobbling motion has been investigated in the nucleus Au-187. A longitudinal wobbling-bands pair has been identified and clearly distinguished from the associated signature-partner band on the basis of angular distribution measurements. Theoretical calculations in the framework of the particle rotor model are found to agree well with the experimental observations. This is the first experimental evidence for longitudinal wobbling bands where the expected signature partner band has also been identified, and establishes this exotic collective mode as a general phenomenon over the nuclear chart.
