Possible hexadecapole states in 96Ru and 128Te studied with the sdg-IBM-2 — •Oriana Diessel, Mark Spieker, and Andreas Zilges — Institute for Nuclear Physics, University of Cologne
Quadrupole excitations of fully-symmetric and mixed-symmetric nature are well established in atomic nuclei [1]. Octupole excitations of both types have also been discussed [2]. Recently, first candidates for mixed-symmetry hexadecapole states have been proposed based on a comparison of experimental data and sdg-IBM-2 calculations [3, 4].
In this contribution, the sdg-IBM-2 calculations for 96Ru and 128Te will be presented and compared to experimental data. Special emphasis will be put on possible hexadecapole-type excitations of both fully-symmetric and mixed-symmetric nature. To further test the hexadecapole phonon as a building block of nuclear structure, possible multiphonon couplings in 128Te will be discussed as well.
