TRANSITION EMISSION FROM THE VERY YOUNG SUPERNOVA REMNANT G25.5+0.2

Interpretation of the spectrum of the very young supernova remnant G25 .5+0.2 in terms of the commonly used mechanisms of synchrotron or ther mal emission runs into serious difficulties. It is shown that the inte nsity distribution over the spectrum of this source is adequately fitt ed with the transition emission (with the density effect taken into ac count) for Thomson scattering of relativistic electrons by magnetic no nuniformities within the shell.
