【 摘 要 】

Electron capture in Be4++ H collisions is studied at collision energies between 1 and 100 keV/u, as a benchmark to discuss the accuracy of different theoretical approaches. Partial cross sections, obtained by solving numerically the time-dependent Schrödinger equation, are compared to the corresponding results from close-coupling and classical trajectory Monte Carlo calculations.
