The impact ionization process of Be by H+ is investigated using the continuum-distorted-wave and the eikonal-initial-state (CDW-EIS) approximation in this paper. The single and double differential cross sections are calculated for the projectile energies ranging from 50keV/u to 10000 keV/u. The total cross sections are consistant well with the previous results. The ionization mechanism of soft-collision, electron captured to continuum states and binary-encounter collisions are discussed. The soft-collision ionization mechanism is the most important contributor to the total cross section. Auger process for Be(1s2s2) is under study by adopting the FAC code.
