MAGNETIC-MOMENTS OF NUCLEI AND G-FACTORS FOR BARYONS AND QUARKS IN SU2 QUANTUM UNIVERSAL ENVELOPING ALGEBRA

The quenching phenomena on the magnetic moments of odd A nuclei have been studied by assuming the shell model configuration of nucleons and SU2 quantum universal enveloping (QUE) algebra. In order to test a q deformation observed from this analysis is universal or not, we have analyzed the magnetic moments of odd-odd nuclei in the same approach, by taking the experimental data of relevant pair of odd A nuclei close in nature as inputs for the chosen odd-odd one. The additional and reasonable values of q deformation found there clearly indicate that the QUE-algebraic angular-momentum coupling rule is realized in nature at least for the composite system. It is pointed out that the DELTA (1232) will contribute so as to smooth out the q to a common finite-ranged value of it.
