Angular distributions of α particles emitted by deformed oriented nuclei

Abstract

Spectroscopic studies of the α decay of 140I have firmly established octupole collectivity in Xe and evinced unique theoretical predictions of a quenched dipole moment. The first detailed investigations of an exotic Xe nucleus, including measurements of half-lives of levels in the ground and octupole bands, were made possible due to a new approach to produce beams of iodine with ISOL sources. © 1999 The American Physical Society.
