Theoretical calculations of the electron capture cross sections in collisio
ns of beryllium ions with helium atoms are performed in a close-coupling me
thod based on molecular-state expansion for the Beq+ (q = 2, 4) ion impacts
below 35 keV amu(-1),and in the continuum distorted-wave method for the Be
q+ (q = 1-4) ion impacts above 100 keV amu(-1). The present results are dis
cussed in comparison with other available theoretical calculations.
