    "abstract": "A generic explanation for the recently observed anomalous crossing\nfrequencies in odd proton rare earth nuclei is given. As an example, the proton\n${1\\over 2} [541]$ band in $^{175}$Ta is discussed in detail by using the\nangular momentum projection theory. It is shown that the quadrupole pairing\ninteraction is decisive in delaying the crossing point and the changes in\ncrossing frequency along the isotope chain are due to the different neutron\nshell fillings.",
