Abstract
We report the detection of two continuum X-ray components in the spect rum of the transient X-ray pulsar EXO 2030+375 at a high state in 1985 . The spectrum of the soft X-ray component could be fitted by a blackb ody-like spectrum with temperature kT approximately 1.1 keV and a radi us of the emsion area R approximately 3.6-6.1 km (assuming 5 kpc dista nce), while the other component was represented by a power law.
