N. Arunachalam et al., EFFECT OF NEUTRON ORBITALS ON THE NUCLEAR SHAPE IN NEUTRON-DEFICIENT AND NEUTRON-RICH ZIRCONIUM NUCLEI, Physical review. C. Nuclear physics, 56(2), 1997, pp. 1183-1186
The neutron-deficient and neutron-rich zirconium nuclei are studied us
ing statistical theory. The deformation dependence of occupation numbe
rs of the neutron orbitals in these nuclei near the Fermi level is inv
estigated. The preference of the neutrons to occupy or vacate a partic
ular orbital is found to contribute a particular shape to the nucleus.
