Abstract
Electron-hydrogen scattering in Debye plasma environments has been investigated using the close-coupling approximation. Three different models, viz. 3-state CCA, 6-state CCA, and 9-state CCA, have been employed in the present investigation. The positions and respective widths of the 2s21Se resonance of hydrogen negative ion have been investigated for various plasma conditions. The inter-particle interactions have been taken to be of Debye-Hückel type. The present results are in close agreement with those of Kar and Ho (New J. Phys., 7 (2005) 141).
