| Abstract: | The self-consistent tilted axis cranking covariant density functional theory based on the point-coupling interaction is applied to investigate the tilted axis rotation in ~(57)Mn.The observed data for band C are reproduced well with the assigned configuration config 1.The shears mechanism for magnetic rotation is examined by investigating microscopically the orientation of angular momentum and the corresponding contributions.It is found that config 1 and config 3 correspond to a rotation of high-K character.Config 2 corresponds to a rotation of magnetic character.However,due to the presence of electromagnetic transition B(M1) and B(E2),collective rotation plays an essential role in the competition with magnetic rotation. |
