On the behavior of the n1(K, T)A n2 series of doubly excited states in He-like atoms immersed in weakly coupled plasmas

ABSTRACT: The stability of resonant states in Helium-like atoms while under the influence of a plasma environment is studied. We analyze the variation of resonance parameters (energies and lifetimes) against the strength of the screening parameter within the Debye-H¨uckel model. We use a Feshbach-li...
