• We study effects of the quadrupole pairing force on the coefficients of the angular-momentum expansion of the rotational energy of the ground band in the framework of the cranking model. We performed numerical calculation according to the self-consistent collective coordinate (SCC) method. In particular, we compare the strengths of the quadrupole pairing force used by a few groups. It is shown that this force remarkably improves the calculated coefficients in the region A≧162 of even Er isotopes, while near the transition region there exists a large discrepancy in the coefficient of the fourth order between experimental and calculated values with any suggested strength. An interpretation on this discrepancy is discussed.
