Study of possible antimagnetic rotation in 100Ru

Abstract

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 ${\Im }^{\left(2\right)}$ 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 ${\Im }^{\left(2\right)}$ and calculated B(E2) values with spin shows the possible antimagnetic rotation character. Additionally, the calculated spin (ħ) versus frequency (MeV) plot of configuration $\pi {\left(g_{9/2}\right)}^{-2}$ ⊗ $\nu \left[h_{11/2}^2{\left(g_{7/2}\right)}^2\right]$, which is comparable with experimental values supports the possibility of the AMR phenomenon in the positive parity band of ¹⁰⁰Ru.
