Abstract.

High-spin states in 163,164Ho were investigated by means of in-beam \(\gamma\)-ray spectroscopy techniques using the multidetector array GASP. Excited states in 163,164Ho were populated predominantly through the incomplete-fusion mechanism in the 160Gd (11B \(,\alpha xn)\) reaction at a beam energy of 61 MeV. Known rotational bands in 163 Ho have been extended to higher spins and a three-quasiparticle band has been observed in this nucleus. Rotational bands have been identified in 164Ho and their configurations have been discussed. Empirical Gallagher-Moszkowski (GM) splitting energies were extracted from the \(\pi 7/2^-[523]\otimes\nu 5/2^-[523]\) and \(\pi 7/2^-[523]\otimes\nu 5/2^ + [642]\) GM doublets. Alignments, band crossing frequencies, and electromagnetic properties have been analyzed in the framework of the cranking model.
