LINO, J.L.S.  y  TORRES, G.G.Z.. Theoretical study of e^- -He scattering using the Schwinger variational principle with plane waves as a trial basis set. Rev. mex. fis. [online]. 2004, vol.50, n.5, pp.427-430. ISSN 0035-001X.

We report an application of the Schwinger variational principle with plane waves as a trial basis set. Differential cross sections are obtained for e^- -He from 15 to 100 eV. Our differential cross is found to be in reasonable agreement with experimental data.

Palabras llave : Schwinger; electron.
