title: Autoionizing 1Se resonance of H- in Debye plasma environments.
abstract: We have made an attempt to investigate atomic resonances in various Debye plasma environments. The 2 s(2) (1)S(e) autoionization resonance for a two-electron system H- is determined by calculating the density of resonance states using the stabilization method. Highly correlated Hylleraas-type wave functions are used to represent the correlation effects between the three charged particles. The calculated resonance energies and widths for the various Debye parameters ranging from infinity to a small value are reported.
