Analysis of new experimental data on theDy160spectrum with the symplectic interacting vector boson model

Abstract

Analysis of the recently obtained experimental data for a lot of collective states of $^{160}\mathrm{Dy}$ is presented. Classification of the low-lying states with positive parity ${0}^{+},{2}^{+},{4}^{+},{6}^{+}$ is performed. The energies of rotational high-spin states of the ground, $S,\ensuremath{\gamma}$ and two negative-parity bands are described in the framework of the interacting vector boson model. The energies of the bands are reproduced with high accuracy using only one set of model parameters for all bands. A more detailed investigation of the results is performed by calculation and comparison with experiment of the high-order odd-even staggering effects between states from different pairs of bands.
