Description
Summary:In this work, non – adiabatic effects manifested in the magnetic properties of low-lying states of even-even deformed nuclei are studied. A simple phenomenological model which takes into account the Coriolis mixing of states of the ground and Kπ = 2+n and Kπ = 1+v bands are proposed. The Calculations for isotopes 160Dy and 170,172,174Yb, are carried out. The calculated gR–factor for the states of ground band which are compared with experimental data. Decreases of gR–factor with increasing angular momentum I have been discussed. The probability of M1–transition from 1+v and coefficients of multipole mixture δ(E2/M1) from 0+2, 0+3, 2+1, and 2+2 bands are calculated and compared with the experimental data. Decreases of gR–factor with increasing angular momentum I have been discussed. That these is an obvious inverse relation between gR – factor and angular momentum I of the ground band states. This has been explained by a mixing ground and Kπ = 1+ bands which have a strong B(M1) to ground state.
