Abstract:
An interpolation method is suggested to calculated the correlation energies ϵmath image{ϱ} and ϵmath image{ϱ} of para- and ferromagnetic states of an homogeneous electron gas of any density ϱ. The functions ϵmath image{ϱ} and ϵmath image{ϱ} plotted in this method reproduce an exact dependence of correlation energy on gas, ϱ, in the limits within ϱ → infin; and ϱ → 0, as well as the empiric correlation energies of atoms. With the obtained functions, ϵmath image and ϵmath image, the possibility of appearance and suppression of ferromagnetism when varying the density of electron gas is investigated. Paramagnetic susceptibility of gas as a function of ϱ is calculated, and the results obtained are compared with the experimental data for Na and K.
