Diffuse x-ray spectrum from 14 to 200 keV as measured on OSO-5
Technical Report

OSTI ID:4357420
The measurement of energy spectrum of the diffuse component of cosmic x- ray flux made on the OSO-5 spacecraft is described. The contributions to the total counting rate of the actively shielded x-ray detector are considered in some detail and the techniques used to eliminate the noncosmic components are described. Positive values for the cosmic flow are obtained in seven energy channels between 14 and 200 keV and two upper limits are obtained between 200 and 254 keV. The results can be fitted by a power law spectrum. A critical comparison is made with the OSO-3 results. Conclusions show that the reported break ln the energy spectrum at 40 keV is probably produced by an erroneous correction for the radioactivity induced in the detector on each passage through the intense charged partlcle flowes in the South Atlantic anomaly.
