Nuclear Mass Distributions From Elastic Scattering Of Low-Energy Alpha-Particles

The microscopic model is applied to the elastic scattering of α-particles from 204, 206, 208 Pb and 209 Bi below and near the Coulomb barrier. The analysis shows that the root-mean-square radii of the nuclear mass distributions do not exceed the values of the charge rms radii by more than 0.1 fm.
