The decay of the triaxial superdeformed band in 163Lu (W. Schmitz et al., Phys. Lett. B 303, 230 (1993)) was investigated using the Euroball spectrometer array. High-spin states were populated in the reaction 139La(29Si,5n)163Lu at 145 MeV at the tandem XTU accelerator of the INFN Legnaro. Coincidence relationships and DCO ratios are determined for the linking transitions. From these data a spin assignment is derived for the band which confirms the previously suggested N = 6 proton configuration.
