Abstract

Lifetimes of excited states of positive and negative parity \(\Delta \)I = 2 bands of \(^{106}\)Cd have been measured using the Doppler Shift Attenuation Method (DSAM). The electric quadrupole reduced transition probability rates, B(E2), show a significant decreasing trend with increasing spin along with large observed \(\Im ^{(2)}\)/B(E2) values. The experimental observations, interpreted in the framework of semiclassical particle-rotor model (SCM) calculations, suggest that these bands have the character of twin-shears type anti-magnetic rotational bands resulting from the coupling of g\(_{9/2}\) proton holes with h\(_{11/2}\), g\(_{9/2}\) and d\(_{5/2}\) neutron particles. Another negative-parity band in the same nucleus has been studied using SCM, which also interprets it to be an anti-magnetic rotational band.
