Nuclear superfluidity for antimagnetic rotation in ${}^{105}$Cd and ${}^{106}$Cd

Abstract

The effect of nuclear superfluidity on antimagnetic rotation bands in ${}^{105}$Cd and ${}^{106}$Cd are investigated by the cranked shell model with the pairing correlations and the blocking effects treated by a particle-number conserving method. The experimental moments of inertia and the reduced $B(E2)$ transition values are excellently reproduced. The nuclear superfluidity is essential to reproduce the experimental moments of inertia. The two-shears-like mechanism for the antimagnetic rotation is investigated by examining the shears angle, i.e., the closing of the two proton hole angular momenta, and its sensitive dependence on the nuclear superfluidity is revealed.
