摘　　要：By solving a time-dependent Schrodinger equation（TDSE）, we studied the electron capture process in the He^2＋＋ H collision system under a strong magnetic field in a wide projectile energy range. The strong enhancement of the total charge transfer cross section is observed for the projectile energy below 2.0 ke V/u. With the projectile energy increasing, the cross sections will reduce a little and then increase again, compared with those in the field-free case. The cross sections to the states with different magnetic quantum numbers are presented and analyzed where the influence due to Zeeman splitting is obviously found, especially in the low projectile energy region. The comparison with other models is made and the tendency of the cross section varying with the projectile energy is found closer to that from other close coupling models.By solving a time-dependent Schrodinger equation（TDSE）, we studied the electron capture process in the He^2＋＋ H collision system under a strong magnetic field in a wide projectile energy range.
