P. Sadykova, W. Ebeling, I. M. Tkachenko] Abstract.: The electron-electron, electron-ion, ion-ion and charge-charge static structure factors are calculated for alkali (at T = 30 000K, 60 000K, n e = 0.7 × 1021 ÷ 1.1 × 1022cm-3) and Be2+ (at T = 20eV, n e = 2.5 × 1023cm-3) plasmas using the method described by Gregori etal. The dynamic structure factors for alkali plasmas are calculated at T = 30 000K, n e = 1.74 × 1020, 1.11 × 1022cm-3 using the method of moments developed by Adamjan etal. In both methods the screened Hellmann-Gurskii-Krasko potential, obtained on the basis of Bogolyubov's method, has been used taking into account not only the quantum-mechanical effects but also the repulsion due to the Pauli exclusion principle. The repulsive part of the Hellmann-Gurskii-Krasko (HGK) potential reflects important features of the ion structure. Our results on the static structure factors for Be2+ plasma deviate from the data obtained by Gregori etal., while our dynamic structure factors are in a reasonable agreement with those of Adamyan etal.: at higher values ofk and with increasing k the curves damp down while at lower values of k, and especially at higher electron coupling, we observe sharp peaks also reported in the mentioned work. For lower electron coupling the dynamic structure factors of Li+, Na+, K+, Rb+ and Cs+ do not differ while at higher electron coupling these curves split. As the number of shell electrons increases from Li+ to Cs+ the curves shift in the direction of low absolute value of ω and their heights diminish. We conclude that the short range forces, which we take into account by means of the HGK model potential, which deviates from the Coulomb and Deutsch ones, influence the static and dynamic structure factors significantly.
