Abstract

The decay sequence based on the 5/2⁺(402) proton orbital has been identified in ¹⁷¹Re up to spin 41/2. An anomalous upbend in the alignment is observed below the expected backbend, a phenomenon similar to that observed in the yrast sequence of ¹⁷²Os. The properties of the 5/2⁺(402) band can be understood in terms of two crossings, one at low spin with a band based on a deformed intruder configuration, the second at higher spin with a band composed of aligned i_13/2 neutrons.
