Abstract
Two-pair excitations in a homogeneous electron gas are investigated wi thin screened second order perturbation theory. Based on a suggestion by Ichimaru [K. Utsumi and S. Ichimaru, Phys. Rev. B 22 (1980) 5203] a n additional method of obtaining the effective interelectron interacti on is presented. A closer inspection of the basic equation, rewritten as a self-consistency problem, justifies the use of static screening w ithin this model. Fit formulae for all main results are made available . Finally, an application of these calculations to the problem of prot on stopping in aluminium is presented, which is in good agreement with the experiment.
