Özet
In this study, using a rotational invariant microscopic model which is free from any adjustable parameter in the random phase approximation, the total M1 transition intensities of the 1 + levels arising from the scissors mode for the Ce isotopes up to 4 MeV have been calculated and their dependence on the square of the deformation parameter δ 2 has been investigated. In the Ce isotopes, the dependence of the total B (M1) transition on δ 2 is linear as in the case of Nd and Sm isotopes. The separation of the rotational branch from the 1 + states causes the fragmentation of the scissors mode and the collectivization of low-lying states.
