• Integral elastic scattering cross sections of Li^+ ions scattered through effective laboratory angles greater than 5×10^<-3> rad in collision with Ne, Ar, and Kr atoms at room temperatures were measured in the ion energy range of 500-4000 eV. The repulsive potentials derived from the cross sections are represented by the following analytical formulas: Li^+-Ne: V(r)=1620exp(-5.30r) 1.0<r<1.5, -Ar: V(r)=1750exp(-4.24r) 1.3<r<1.9, and -Kr: V(r)=2210exp(-4.08r) 1.4<r<2.0, where V(r) and r are in units of eV and Å, respectively. Repulsive potentials for the Ne-Ne, Ar-Ar, Kr-Kr, and Li^+-Li^+ systems were also deduced by applying the combining rule to the potentials for the Li^+-rare-gas systems. The results are in reasonable agreement with those published by other workers in the potential range between 10eV and several tenths of an eV.
