【 摘 要 】

Fully differential cross section (FDCS) for the transfer excitation (H++ He → H+He+∗) at high proton energies (630-1200 keV) is studied both experimentally and theoretically within the simplest Plane Wave First Born Approximation (PWFBA). The role of angular correlations in a trial helium ground state wave function is demonstrated.
