Within the framework of the rotating wave approximation the elastic scattering
of electrons by metastable 2s state of hydrogen atoms is studied in the presence
of a resonant laser field. The frequency of the circularly polarized laser
field is chosen to match the 2s-3p transition frequency in
the hydrogen atom. Variation of the cross section with laser intensity
and with incident electron energy (50-150 eV) is
investigated.
