The study of possibility of antimagnetic rotation in 100Ru is studied on the basis of semiclassical particle-rotor model (SCM). In the high spin range 18+ to 28+, the dynamic moment of inertia falls within the typical range of antimagnetic rotation. The decrease in calculated transition probability B(E2) values with an increase in spin, and a sharp increase in the ratio of observed and calculated B(E2) values with spin shows the possible antimagnetic rotation character. Additionally, the calculated spin (ħ) versus frequency (MeV) plot of configuration ⊗ , which is comparable with experimental values supports the possibility of the AMR phenomenon in the positive parity band of 100Ru.
