ABSTRACT:
A final state wave function of multiple scattering theory developed by Das and
seal is utilized in the present study to calculate the triple differential cross sections
(TDCS) for the ionization of metastable 3S state hydrogen atoms at incident
electron energy of 250 eV with the exchange effects in the asymmetric
coplanar geometry for various kinematic conditions. Our present calculation
results are compared with the available hydrogenic ground state experimental
data and other existing theoretical results. A good qualitative agreement is
shown with those of compared results of the present study specifically with
hydrogenic ground state experimental data and metastable 2S and 2P state
with exchange effect results. These new results offer an extensive scope for
experimental verification in such ionization process.
