| Abstract: | Fast time spectral measurements of a gamma-ray burst acquired with a satellite-borne cooled germanium spectrometer during the 18 December, 1972 event indicate significant spectral variations during the course of the event. These data are compared with the results of other exerimenters providing additional evidence for spectral variations on short time scales. The fast time spectra are also compared with spectral measurements obtained by others with accumulation periods longer than typical time widths of the structure in the intensity profile and particularly with spectra averaged over the entire duration of the burst event.Paper presented at the COSPAR Symposium on Fast Transients in X- and Gamma-Rays, held at Varna, Bulgaria, 29–31 May, 1975. |
