Atomic processes under varying plasma environments

We present a quantitative estimate for a number of atomic properties based of the use of Debye-Huckel (DH) screening Coulomb and modified DH screening potential for a charged particle in a plasma [1]. We will examine the variation of the ionization thresholds and the resulting reduction in the number of bound excited states of atoms. The effect on the atomic transitions and doubly excited resonance widths will also be studied in detail. \\[4pt] [1] P. K. Shukla and B. Eliasson, Phys. Lett. A 372, 2897 (2008).
