Deviations from theI(I+1)Law in Deformed Nuclei

The perturbation of the single-particle motion by rotation, in deformed nuclei, produces a change in the potential-energy surface. In this work, the values of the collective nuclear parameters are obtained as a function of the angular momentum $I$ by minimizing the expectation value of the Hamiltonian for each value of $I$. In this way, a natural extension of the previous methods used in computing these energy surfaces enables one to calculate the deviations from the $I(I+1\mathrm{})\mathrm{}$ law corresponding to rigid rotors. Comparisons with experimental data and previous theoretical calculations are included.
