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 K super([pi]) = 2 super(+) sub(n) and K super([pi]) = 1 super(+) sub([nu]) bands are proposed. The Calculations for isotopes super(160)Dy and super(170,172,174)Yb, are carried out. The calculated g sub(R)- factor for the states of ground band which are compared with experimental data. Decreases of g sub(R)- factor with increasing angular momentum I have been discussed. The probability of M1- transition from 1 super(+) sub([nu]) and coefficients of multipole mixture delta (E2/M1) from 0 super(+) sub(2), 0 super(+) sub(3), 2 super(+) sub(1), and 2 super(+) sub(2) bands are calculated and compared with the experimental data. Decreases of g sub(R)- factor with increasing angular momentum I have been discussed. That these is an obvious inverse relation between g sub(R)- factor and angular momentum I of the ground band states. This has been explained by a mixing ground and K super([pi]) = 1 super(+) bands which have a strong B(M1) to ground state.
