In recent years the substantial materials were collected on the levels o f m-mHf /1 ,2/. Rotation states o f low spins obtained as a result o f the dissociation maternal nuclearl727a,l747a, mLu, mLu, m Ta,mLu 111. States o f the high spins were determined in nuclear reactions 111. All five isotopes o f the Hf are deformed nuclear. Many developed o f rotational bands were obtained. In some o f the
y - band, even and odd movements were observed. In the nuclear o f '"‘Hf nuclear the y -b a n d is close to the (3, band. Similarly, the m'Hf y - band is close to the p, - band. The mixing parameters o f wave functions o f the states o f the low-lying rotational bands are related to this.
In this research spectroscopic characteristics o f low-lying states mentioned above are investigated through phenomenological model 131, in which Coriolis mixing is considered o f states the o f the ground gr(0^)-, PTO^-PA0?)- y(2+) ~ vibrations and K ” = r - rotational bands.
Spectrum o f energy o f the positive parity states was calculated. Values inertial parameters o f rotation core were obtained from /4/. The positive parity states were theoretically analyzed. In

The structure o f the excited levels is discussed. The influence o f the effect o f the m ixing on the spectroscopic characteristics o f the low-lying states is investigated.
