Abstract
We present ab initio calculations of cross sections for single and autoionizing double electron capture in collisions of with for impact energies between 0.2 and 10 keV/amu. Calculations have been carried out by means of a close-coupling molecular treatment using the sudden approximation for rotation and vibration of the diatomic molecules. Since the molecular states involved are infinitely excited, a configuration interaction method, with a block-diagonalization procedure, has been employed to evaluate potential energy surfaces and dynamical couplings.
