在有限程液滴模型的框架下，考虑轴向和反射不对称性，计算了原子核的电荷半径。此外，为了经验地将动力学贡献包括到半径计算中，我们使用从实验B（E2;01+21+）值推导出的四极形变作为输入参数。据发现，计算出的电荷半径是在质量regionsA 210与测量的电荷半径不太一致< 110 andA>。对于110 <A< 210的模型预测和实验之间的差异，观察到轻微的系统偏差。然而，当用B（E2;01+21+）值代替模型值时，计算的电荷半径沿沿着同位素链的变化与实验值符合得更好。
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 deformationdeduced from the experimentalB(E2;01+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 regionsA< 110 andA> 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’s fromB(E2;01+21+) values are used instead of the model’s.
