p-wave auto-detaching resonances of H- below the n=2 threshold in a Debye plasma medium

p-wave electron-hydrogen scattering has been investigated in a Debye plasma environment employing a close-coupling approximation. Three different basis sets have been used to estimate the resonance parameters. Plasma screening has been taken into account via the Debye-Huckel model potential. Auto-detaching P-1,3(o) resonances of the hydrogen negative ion below the n = 2 threshold have been studied under various plasma conditions. The present predicted resonance energies and widths are in close agreement with those of Kar and Ho (2006 Few Body Syst. 40 13).
