Further examination of prolate-shape dominance in nuclear deformation

Hamamoto-Kuroda, Ikuko LU and Mottelson, Ben R. (2009) In Physical Review C (Nuclear Physics) 79(3).
Abstract
The observed almost complete dominance of prolate over oblate deformations in the ground states of deformed even-even nuclei is related to the splitting of high center dot "surface" orbits in the Nilsson diagram: on the oblate side the occurrence of numerous strongly avoided crossings which reduce the fanning out of the low Lambda orbits, while on the prolate side the same interactions increase the fanning out. It is further demonstrated that the prolate dominance is rather special for the restricted particle number of available nuclei and is not generic for finite systems with mean-field potentials resembling those in atomic nuclei.
