Resonance States of Negative Hydrogen-like Ions in Quantum Plasmas

Abstract

We studied the 1Se and 1,3Po resonance states of negative hydrogen-like ions immersed in quantum plasmas. The exponential cosine screened Coulomb potential was considered to model the quantum plasma environment. The correlated exponential wave functions in which the exponents were generated by a pseudo-random technique were applied to represent the correlation effects between the charged particles. The stabilization method was used to calculate the resonance parameters (position and width). The resonance parameters (position and width) for Ps−, Mμ−, π−, 1H−, D−, T− and ∞H− embedded in quantum plasmas are reported for various screening parameters. The 1Se resonance parameters for Mμ−, π−, 1H−, D−, T− ions and 1,3 Po states for Ps−, Mμ−, π−, 1H−, D−, T− and ∞H− of the proposed systems are reported for the first time in the literature.
