Systematics of triaxial deformation in Xe, Ba, and Ce nuclei
TL;DR: The ([beta],[gamma]) deformation parameters of even-even Xe, Ba, and Ce nuclei have been calculated by using the triaxial rotor model and the smooth dependence of the deformed parameters on [ital Z] and [ital N] is discussed.

Non-yrast states in 125Xe
I. Wiedenhöver,J. Yan,U. Neuneyer,R. Wirowski,P. von Brentano,A. Gelberg,N. Yoshida,Takaharu Otsuka +7 more
TL;DR: In this paper, the non-yrast states of 125 Xe have been investigated by means of in-beam γ-spectroscopy using a setup of 6 Compton-suppressed high-puritygermanium (HPGe)detectors.

Valence mirror nuclei
TL;DR: In this paper, a comparison of examples of "valence mirror nuclei" (nuclei of the type N=82, Z = 60+k and N=60+k, Z=50) 142Nd (144Sm) and 110Sn (112Sn) reveals a remarkable similarity of the level energies of the yrast and yrare states.

Simplified shell model calculations for valence mirror nuclei
R. F. Casten,R. F. Casten,J. Yan,R. Wirowski,A. Gelberg,A. Gelberg,P. von Brentano,D. S. Brenner +7 more
TL;DR: In this article, simplified shell model calculations are carried out by exploiting the valence mirror nucleus concept for the singly magic N = 82 and Sn partners, and special attention is paid to multiplets of negative-parity (primarily seniority ν = 2) states.

Proton-neutron symmetry in valence mirror nuclei
TL;DR: Nuclear states of yrast and yrare type have been investigated in pairs of valence mirror nuclei and the observed similarities can be related to an approximate proton-neutron symmetry in valence Mirror nuclear states.
