In the impulsive phase of solar flares the primary source of plasma heating is collisions between the nonthermal particles and the ambient, thermal plasma in the flare loop. Thus the thermal emission (e.g., soft X-rays) can yield clues to the properties of the nonthermal beam. We have undertaken a study of the nonthermal particle signatures contained within the thermal emission of a flaring coronal loop to test predictions modeled in the dissertation of Winter (2009). Here we study loops as observed in thermal soft X-ray (SXR) emission by the Yohkoh satellite. We present the temperature evolution as viewed in SXR to that predicted by the model, and continue an analysis of the temporal profile of the SXR emission.
