Differential cross sections for electron impact excitation of molecular hydrogen using the momentum-space multichannel optical method

In the present work, the momentum-space multichannel optical method is employed in four-state close-coupling calculations to study the electronic excitation of H₂ molecules by electron-impact. Particularly, differential cross sections for the X¹Σ_g⁺→b³Σ_u⁺, X¹Σ_g⁺→a³Σ_g⁺, and X¹Σ_g⁺→c³Π_u transitions are reported. Comparison is made with the available experimental and theoretical results.
