Magnetic properties of rotational bands in 160Dy and 170–174Yb isotopes
In this work, non - adiabatic effects manifested in the magnetic properties of lowlying 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� = 2+nand K� = 1+� bands are proposed. The Calculat...

Summary: | In this work, non - adiabatic effects manifested in the magnetic properties of lowlying
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� = 2+nand K� = 1+�
bands
are proposed.
The Calculations for isotopes 160Dy and 170;172;174Y b, 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+�
and coefficients of multipole mixture �(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 K� = 1+ bands which
have a strong B(M1) to ground state. |
