Abstract: The quantum statistical theory of collisional rate coefficients of nonideal plasmas, developed in some recent papers for hydrogen, is applied to calculate the impact ionization and three-body recombination coefficients for the valence electron of the atoms in Li-, Na-, K-, Rb- and Cs-plasmas. The many-body effects are included by static screening in the quasiparticle energy shifts and in the effective potentials. Because the ionization of alkali atoms represents a multielectron problem, an effective two-body electron-ion potential is derived using the method of close coupling equations of quantum scattering theory. The latter is replaced by a suited two-parametric pseudopotential taking into account the shielding effects of the inner shell atomic electrons. Finally, numerical results are given for the ionization cross sections and the rate coefficients.
