Open full text 15 citations

Abstract

Low-lying bands arising out of the coupling of a g boson (hexadecupole vibration) to the SU(5), SU(3) and O(6) limits of the interacting boson model are classified. Closed analytic expressions for energies and E2 and E4 transition matrix elements are derived for the 1g-boson bands in each of the three limiting cases. These results are used in investigating the hexadecupole vibrational nature of some of the levels/bands in Cd, 156 Gd, 178 Hf and Os isotopes.
