• The Coulomb-Born approximation is applied to obtain total cross sections of charge transfer reacton between a highly-ionized atom and a proton. The final from of the scattering amplitude is expressed in one dimensional integral to be evaluated numerically. The total cross section is calculated by numerical integration over scattering angles. Target atoms studied are C, O, Ne, Ar, Fe, Cu, Nb and Mo, because a considerable amount of their ions is found as impurities in fusion plasmas. Very small cross sections less than 10^<-22>∼10^<-24> cm^2 are obtained for highly-ionized metalic ion-targets (such as Fe, Cu Nb and Mo). The Coulomb repulsion between the target and the projectile was found to cause a rapid decrease of the cross section as the relative kinetic energy decreases.
