Total cross sections and astrophysical S factors of the radiative capture reactions ..cap alpha..( /sup 3/He,..gamma..)/sup 7/Be and ..cap alpha..(t,..gamma..) /sup 7/Li are investigated by the resonating-group method. The theoretical value of the S factor at E/sub c.m./ = 10 keV is predicted to be 0.508 keVxb without the use of any artificial parameters. An interesting difference between the mirror reactions is found and theoretically explained.
