Possible antimagnetic rotation in 101Ru

The semiclassical particle-rotor model (SCM) has been used for the calculation of reduced electric quadrupole transition rates B(E2) for the [Formula: see text] negative parity band in [Formula: see text]Ru. The B(E2) values are found to exhibit a decreasing behavior with increasing spin values in the range 27/2 [Formula: see text] I [Formula: see text] 47/2 [Formula: see text]. For the higher spin states, the experimental dynamic moment of inertia [Formula: see text] is also in the range of AMR bands. The calculation of spin ([Formula: see text]) versus frequency (MeV) for the [Formula: see text] configuration with the core contribution of 2 [Formula: see text] is found to be in good agreement with the experimental results and favors the possibility of AMR phenomenon in [Formula: see text] negative parity band in [Formula: see text]Ru.
