Short Note

Abstract.

High-spin states in the odd-proton nucleus 173Lu have been populated in a 170Er(7Li,4n) reaction and the emitted \(\gamma\)-radiation was detected with the GASP array. The favoured and unfavoured sequences of the \(\pi 1/2^- [541]\) band have been considerably extended. The favoured sequence does not show any indication of a band crossing up to a rotational frequency of \(\approx\) 0.45 MeV. This is the largest crossing frequency ever observed for 1/2- [541] bands of odd-proton nuclei with \(67 \leq Z \leq 77\) and \(90 \leq N \leq 106\). Previous Cranked Shell Model (CSM) calculations underestimate the crossing frequency by 100 keV.
