| Abstract: | We present a new two-component method of fitting spectra of cosmic gamma-ray bursts, to get some information about the emission regions through this kind of fit. Our results support the existence of structure in the thin emission sheet. The peak appearing at about 780 ke V in the spectrum of GB 7811193 seems not to be a one-photon annihilation line.Project supported by the National Nature Science Foundation of China. |
