- Abstract
High-spin states in the odd-proton nucleus 173Lu have been populated in a 170Er(7Li,4n) reaction and the emitted γ-radiation was detected with the GASP array. The favoured and unfavoured sequences of the π1/2- [541] band have been considerably extended. The favoured sequence does not show any indication of a band crossing up to a rotational frequency of ≈ 0.45 MeV. This is the largest crossing frequency ever observed for 1/2- [541] bands of odd-proton nuclei with 67 < Z < 77 and 90 < N < 106. Previous Cranked Shell Model (CSM) calculations underestimate the crossing frequency by 100 keV.
