Abstract: A careful investigation of a CCD spectrum of the SB1 system kappa Cnc in the spectral region 3800 - 8000 Angstroms resulted in the discovery of the lines of the secondary star. We then analyzed several short-wavelength range Reticon spectra obtained at different orbital phases to find additional radial velocities. The mass ratio is m(A)/m(B) = 2.2 +/- 0.1 and, from binary spectrum-synthesis, the ratio of radii R(A)/R(B) is greater or equal to 2.
