This paper presents theoretical results for the influence of plasma electron-electron collisions in correlated proton stopping forces. First calculations of the effects of these collisions on the vicinage forces for plasma matter are shown. In particular, these effects are studied in a Te = 10 eV and n = 1023 cm−3 plasma yielding a self-retarding proton force increased more than 11% at maximum value. Also vicinage forces enhances more than 15% in the analyzed cases. All this implies that plasma electron-electron collisions play an important role both in non and correlated ion stopping and must be considered for any application of ion energy deposition in plasma matter.
