Abstract. High-spin states in the odd-odd nucleus 172Lu have been populated in a 170Er(7Li, 5n) reaction and the emitted $\gamma$ -radiation was detected with the GASP array. Two sequences of a new identical band have been observed with the transition energies in the favoured and unfavoured sequences being identical within $\approx 3$ keV at low spins and $\approx 1$ keV at high spins over the whole observed spin range. Aninterpretation as a pseudo-spin singlet band of $\pi 1/2^- [541] \otimes \nu 1/2^- [\widetilde{420}]$ configuration is proposed. It represents the best example of a pseudo-spin singlet band in normal deformed nuclei known until now.
