TITLE: Polarization effects in the scattering of electrons
by nuclei
PERIODICAL: Uhrayinslkyy fizychnyy zhurnal, v. 5, no. 4, 1960,

T F,'4,,.r: The scattering cross-section, the azimuthal asymmetry and
the polarization of the scattered electrons are calculated. Elec-
tron scattering by nuclei with Yuhawa charge-density distribution
is considered in the second Born- approximation. The Yultawa charge-
density distribution is
P(r) - X2-e--"r (4)

For describing the polarization of the scattered electrons, the
method of density matrices is used. For the cros-9-section one-ob-
