Abstract:
In this paper we aim to understand the low lying nuclear excitations in the vibrational odd-A nuclei.
The particle-core coupling model has been applied to nuclei whose structure can be approximated by a nucleon coupled to a collective vibrator ( even-even core). In this case, the nucleon-core interaction potential contains, besides the central term, a term representing the interaction of the odd nucleon with the vibrations of the core.
In oder to perform the numerical calculations we adapted a computer code which diagonalizes the hamiltonian considering only the quadrupole and octupole phonons. The coupling strength between the single particle levels and the phonons was chosen in order to obtain a good description of the experimental energy spectrum. Further on the dipole magnetic moments, the quadrupole electric moments and the reduced transition probabilities have been calculated. A good description of experimental data has been obtained for odd-A Sb nuclei.
In the near future we plan to run experiments guided by the predictions of the present calculations.
