| 内容記述 | The propagation, confinement and total energy of energetic (greater than 25 keV) electrons in solar flares are examined through a brief review of the following hard X-ray measurements: (1) spatially resolved observations obtained by imaging instruments; (2) stereoscopic observations of partially occulted sources providing radial (vertical) spatial resolution; and (3) directivity of the emission measured through stereoscopic observations and the center-to-limb variation of the occurrence frequency of hard X-ray flares. The characteristics of the energetic electrons are found to be quite distinct in impulsive and gradual hard X-ray flares. In impulsive flares the nonthermal electron spectrum seems to extend down to about 2 keV, indicating that the total energy of nonthermal electrons is much larger than that assumed in the past. |
