Abstract
Emission in resonance lines of Fe XXV and Fe XXVI ions is calculated f or the binary SS 433 using the model of colliding stellar winds. Compu ted values of iron lines intensity coincide with observed spectral fea tures for quanta energy about 6.8 keV, if a normal cosmic abundance of iron is assumed. Emission of the continuous spectrum in energy range 6 to 30 keV is calculated. Computed values of total luminosity and ene rgy distribution in the X-ray continuum agree with observational resul ts for SS 433, if a mass-loss rate about 10(-4) M(.) year-1 and a velo city of wind from 2000 to 3000 km sec-1 are assumed.
