| Abstract: | The electron momentum spectra of He(2 1S ) and He(2 3S ) is presented for the first time by calculating the triple differential cross sections (TDCS) for electron impact ionization of helium from the metastable states 2 1S and 2 3S in the non-coplanar symmetric geometry. The incident energy is an order of 1keV. The final state correlations between the scattered and ejected electrons in the continuum and the electron in the residual ion have been considered. The plane wave impulse approximation (PWIA) has also been performed for comparison. |
