In the present work the spectra of even–even Hf isotopes are studied
through the selecting of core–cluster decomposition of the parent nucleus.
The considered partition should give internal stability of the core–cluster
combination. The modified Woods–Saxon and Coulomb potentials are used
to reproduce the spectra of even–even Hf isotopes where the core-radius is
taken as a free parameter. The theoretical calculations of the excitation
energies and the transition probabilities B(E2) of the ground state band
are compared to the experimental data of the considered Hf isotopes. The
obtained results reflect the ability of describing the pure rotational ground
state band of even–even Hf isotopes through the core–cluster decomposition
model.
