Study of antimagnetic rotation in 109,111Cd

The reduced electric quadrupole transition rates have been calculated for the states of the negative parity bands in [Formula: see text]Cd nuclei using semiclassical model (SCM). The calculated transition rates are found to be decreasing with increasing spin for the states above [Formula: see text] and the dynamic moment of inertia [Formula: see text] of the higher spin states are found to be almost constant. The calculated B(E2) values show better agreement with the experimental B(E2) values for [Formula: see text]Cd. The results for both [Formula: see text]Cd and [Formula: see text]Cd nuclei show a very rapidly increasing value of the [Formula: see text] ratio with increasing spin, suggesting the antimagnetic rotational character of the states lying above the spins [Formula: see text] and [Formula: see text], respectively.

Interplay between antimagnetic and collective rotation in 58Fe

The self-consistent tilted axis cranking covariant density functional theory based on the point-coupling interaction PC-PK1 is applied to investigate the possible existence of antimagnetic rotation in the nucleus [Formula: see text]Fe. The observed data for Bands 3 and 4 are reproduced well with two assigned configurations. It is found that the interplay between antimagnetic rotation and collective motion plays an essential role in both bands due to the presence of considerable deformation. In particular, for Band 4, collective rotation is dominant in the competition with antimagnetic rotation. Moreover, it is shown that the behavior of the ratios between the dynamic moments of inertia and the [Formula: see text] values reflects the interplay between antimagnetic and collective rotation.
