Abstract
We calculate the charge radii of nuclei in the frame of the finite-range droplet model including axial and reflection asymmetry. In addition, in order to empirically include dynamic contributions into the radius calculations, we use the quadrupole deformation \( \beta_{{2}}^{}\) deduced from the experimental B(E2;01 + \( \rightarrow\) 21 +) value as an input parameter. It is found that the calculated charge radii are in poor agreement with measured charge radii in the mass regions A < 110 and A > 210 . A slight systematic deviation is observed for the difference between model predictions and experiment for 110 < A < 210 . However calculated changes of charge radii along isotope chains are in better agreement with the experimental data when \( \beta_{{2}}^{}\) ’s from B(E2;01 + \( \rightarrow\) 21 +) values are used instead of the model \( \beta_{{2}}^{}\) ’s.
