Abstract We investigate the cross sections of the elastic electron or positron scattering from ²⁰⁸Pb, ¹²C, ^12,16O and ^28,32S by the relativistic partial-wave expansion method using the static charge density distribution from the self-consistent relativistic mean field model and also calculate the charge form factor for ^12,16O and ^28,32S. The numerical results are compared with the available data. Calculations indicate that the extended charge density distributions of¹²O and ²⁸S have observable effects on the cross sections of the electron or positron scattering as well as the charge form factors.
