Charge radii in modern macroscopic-microscopic mass models; The Role of dynamic quadrupole deformation

Iimura, Hideki  ; Buchinger, F.*

For the nuclei where axially asymmetric or reflection-asymmetric shapes are expected, we calculated the nuclear charge radii by using the Finite Range Droplet Model. As a result, we found the agreement between the experimental and theoretical radii becomes better when these asymmetries are taken into account in the model calculation. In addition, we developed a method to empirically calculate the charge radii of even-even nuclei. This method is based on the Finite Range Liquid Drop Model, and use the experimental (2) value or the excitation energy of the first excited 2 state as input parameters.
