On the physical significance of q-deformation to isovector pairing interactions in nuclei

The quantum deformation concept is applied to a study of isovector pairing correlations in nuclei of the mass 40<A<100 region. While the non-deformed (q -> 1) limit of the theory provides a reasonable global estimate for strength parameters of the pairing interaction, the results show that the q-deformation plays a significant role in understanding higher-order effects in the interaction.
