Charge radii in macroscopic-microscopic mass models of axial asymmetry

Iimura, Hideki  ; Buchinger, F.*

We show that the charge radii of axially asymmetric nuclei calculated in the frame of finite-range droplet model are in better agreement with measured charge radii when axial asymmetry is taken into account. This improvement is mainly the result of a new set of ground-state quadrupole deformations , generated when masses are calculated including axial asymmetry, and to a much lesser degree due to the inclusion of the axial asymmetry in the calculation of the charge radii itself.
