Test of the coherent state approach in the axially deformed region

Coherent State Approach on the Interacting Boson Model (IBM) is tested between the axially deformed and γ-soft transitional regions. Excitation energies of the bands are obtained for the simple IBM Hamiltonian written for this region. Deformation parameter which minimizes the energy of the state is found in a closed form as a function of boson number for each band. Then energy of state within the band is defined by using the moment of inertia obtained from the solution of cranking problem. Matrix elements of quadrupole moment operator and reduced electric quadrupole transitions are given. Then the Coherent State Approach is tested in the case of some selected Hf isotopes.
