Details of the new methodology are presented. In both S38 and S40 there is a fine balance between the proton and neutron contributions to the magnetic moments. Shell-model calculations that describe the level schemes and quadrupole properties of these nuclei also give a satisfactory explanation of the g factors. In S38 the g factor is extremely sensitive to the occupation of the neutron p3/2 orbit above the N=28 shell gap as occupation of this orbit strongly affects the proton configuration. The g factor of deformed S40 does not resemble that of a conventional collective nucleus because spin contributions are more important than usual. © 2006 The American Physical Society.
