Abstract
Using Hartree-Fock-Slater wave functions, values of the nuclear hexadecapole antishielding factor have been calculated for the following ions: , , , , , , , , , , , , , , , , , , , , and . The radial distortions induced in the core electrons due to nuclear hexadecapole moment were calculated using Sternheimer's perturbation numerical procedure. The contribution to due to the shell is much weaker in magnitude than that from the shell. In the three series of ions considered here, maximum values of are obtained in the cases of , , and ions, respectively, where the outer shell is complete and is most external. With the assumption that a large nuclear quadrupole moment may be associated with a significant hexadecapole moment, it is suggested that of the systems examined here containing nuclei with spin , , , , , and are likely to exhibit prominently nuclear hexadecapole interaction effects since these have favorable natural abundance, quadrupole moment, magnetic resonance sensitivity, and large values.
