Elastic scattering of electrons with energy 225 MeV by the nuclei of the isotopes /sup 78//sup ,//sup 80/Se

Differential cross sections have been measured for elastic scattering of 225-MeV electrons by the nuclei of the isotopes /sup 78//sup ,//sup 80/Se in the range of effective transferred momenta 0.42--1.68 fm/sup -1/. The phase-shift analysis of the cross sections is carried out for five charge-density distributions. All charge-density distributions indicate a decrease of the surface-layer thickness for /sup 80/Se in comparison with /sup 78/Se. The experimental data are compared with calculations by the Hartree-Fock method.
