Abstract
Excitation of hydrogen atom from its metastable 2s-state to ns (n = 3,4,5,6) and np (n = 3) states by electron impact has been investigated by employing a distorted-wave method, in the framework of the two-potential formulation. Contribution of exchange has been included by antisymmetrising the total wave function of the system. The differential cross-sections are reported at intermediate energies. Theoretical findings for 2s-5s and 2s-6s transitions have not been reported earlier.
