Abstract
Three new bands in 174Ta have been identified by using the 160Gd(19F,5n) reaction at beam energies of 87 MeV and 96 MeV. Nilsson configurations are assigned to these bands. In the 9/2-[514]p+5/2-[512]n band, the AB neutron crossing occurs at a rotational frequency of  0.30 MeV. This is indicative of the disappearance of the evidence for a reduction in neutron pair correlations.
