摘要：

We present the results of our analysis of the observations of the intermediate polar V2400 Oph by the INTEGRAL and RXTE observatories. We reconstructed the spectrum of the source over a wide (3-100 keV) energy range. The spectrum obtained can be fitted by a computed theoretical model of the post-shock emitting region with T-max similar to 22 keV. As a result, we estimated the mass (0.59M(circle dot)) and radius (8.8 x 10(8) cm) of the white dwarf in the system V2400 Oph. (C) 2004 MAIK "Nauka/Interperiodica".
