Observations of the 283 s X-ray pulsations from 3U 0900--40 (=Vela X-1) over a 36 day interval have led to a determination of the orbital elements for the X-ray star. These elements yield an X-ray mass function f (M) =18.5 +- 0.8 M/sub sun/ and, when combined with the results of optical studies of the companion star HD 77581, give a probable lower limit of 1.4 M/sub sun/ to the mass of the X-ray star.
