The Solar Coronal X-Ray Spectrum 5.5-12 A.
Abstract
Solar X-ray spectra in the wavelength range 5.5-12 a have been measured by the SOLEX spectrometers aboard the USAF p78-1 satellite. The spectra were measured under a variety of flaring and nonflaring conditions. High sensitivity, attained by summing data from several successive spectral scans, enabled the detection of 85 lines, 22 of which remain unidentified, in this wavelength range. In addition, observations of many strong lines were possible with individual scans during the course of the flare evolution. This capability, coupled with the availability of nonflare spectra, facilitated the identification of several lines. The lines of Fe XXII-XXIV are especially important in this wavelength range. For many of these lines, theoretical and observed line strengths
