Study of nuclear shapes of some even nuclei

In Davydov asymmetric rotor (β – fixed, γ – fixed) the effect of (ΔK = 2) to state mixing is a classical illustration where γ and ground state levels of energy are plotted against the asymmetric defamation γ of the nucleus. For γ close to 00 , the Davydove model gives the symmetric rotor 'γ – band' energies. As γ increases the levels of γ – band decreases rapidly in energy and hence the even spin levels of the γ – band interact more and more with their partners in the ground band. The effect becomes extreme above γ = 20. In the present work the authors try to verify whether the nuclei proposed above except ¹⁷⁰Er, are associated with triaxiality and if yes than to what extent. Attempts have been made to discuss ¹¹²Ru in recent past but, only γ – band is considered and not the γγ – band while we consider it to take essential γ – band as well as γγ – band together since both are generated simultaneously by rigid rotor of Davydov
