| Abstract: | We calculate the total electron-capture cross sections for colliding systems: H 2 e B 2 e, B 3 , C 4 , N 5 , O 6 and H 2 e Li( 1s 22s ) by two-state atomic expansion method. Our results are in good agreement with the experimental values at the intermediate-high energy range |

| Keywords: | Atom collision Two-state atomic expansion method Capture cross sections |
