Shielding effect of quantum plasma

Abstract

Numerical comparisons of five screened potentials of dense plasma, namely, ion-sphere, Thomas-Fermi, generalized exponential-cosine, Shukla-Eliasson (SE), and Akbari-Moghanjoughi (AM), are conducted. Bound energy levels of ions in quantum plasma are calculated using the five screened potentials. Our results show that AM and SE models are different from the other three models.
