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 νh11/2 negative parity band in 101Ru. The B(E2) values are found to exhibit a decreasing behavior with increasing spin values in the range 27/2 ℏ≤ I ≤ 47/2 ℏ. For the higher spin states, the experimental dynamic moment of inertia ℑ(2) is also in the range of AMR bands. The calculation of spin (ℏ) versus frequency (MeV) for the π(g9/2)−2⊗ν[h11/2(g7/2)2] configuration with the core contribution of 2 ℏ is found to be in good agreement with the experimental results and favors the possibility of AMR phenomenon in νh11/2 negative parity band in 101Ru.
