Popis:	The energy spectra and electromagnetic transition probabilities of the negative-parity yrast states in odd-A Lu isotopes (Z=71) are investigated systematically using the particle-rotor model and are compared with experimental data before and after the band crossing. It is noted that the moment of inertia of the core after the band crossing is as much a smooth function of the total angular momentum I, as that before the band crossing and can be described by the ab formula. Appreciably different are the triaxial deformations before (similar to 20 degrees) and after (similar to+10 degrees) the band crossing for Lu-161,Lu-163,Lu-165, while they are more or less similar (similar to-10 degrees) for Lu-167 determined from the calculation.
