Revised interpretations for Kπ=1+ bands in Ho166

Experimental data from the Ho165(d,p)166Ho reaction were analyzed using the distorted-wave Born approximation formalism and Nilsson model wave functions with Coriolis mixing. It is concluded that the Kπ=1+ bands at 426 and 568 keV in Ho166 have the 7/2-[523]π-5/2-[512]ν and the 7/2-[523]π-5/2-[523]ν two-quasiparticle configurations, respectively. These assignments interchange the ones currently adopted for these two bands, but are in agreement with phenomenological and theoretical predictions. In addition, the (d,p) data suggest a tentative 7/2-[523]π-1/2-[510]ν assignment for the Kπ=3+ band based at 814 keV in Ho166.
