High-dispersion (5-9 A/mm) spectrograms of Alpha Cam were taken between 1976 and 1985 with the main stellar spectrograph of the 6-m reflector of the Special Astrophysical Observatory of the USSR Academy of Sciences and with the coude spectrograph of the 2-m telescope at the Shemakha Astrophysical Observatory. Measurements of radial velocities v(r) indicated that the runaway star Alpha Cam is a double one. The values of v(r) were found to vary with a period of 3.6784 d and a semiamplitude of 9.0 km/sec, the binary system having an eccentric (e = 0.45) orbit.
