Abstract

The first-order Born approximation with correct boundary condition is applied in a study of the resonant double electron capture by fast He2+ from helium. A configuration-interaction wave function is employed to describe the ground state of helium. Total cross section as a function of the impact energy is calculated and compared with experimental and theoretical values.
