“Anomalous” signature splitting in the yrast band of the odd-odd 160Ho nucleus

Abstract The ( 11 B, 5n) reaction has been used to study the yrast band in 160 Ho up to high spin states ( I = 24). A careful analysis of the experimental odd-even staggering of the [i 13 2 ] n [h 11 2 ] p band reveals in “anomalous” signature splitting for this configuration. This effect is compatible with a small triaxial deformation γ = 5°.
