In Hartree-Fock calcualtions using nonrelativistic and relativistic models we see a change in sign from positive to negative of the hexadecapole moment with mass number around [ital A]=170. Analysis of Hartree-Fock orbitals shows that a group of neutron orbits with large negative hexadecapole moments occur together at the Fermi surface near [ital N]=100 and are responsible for the shape change.
