Abstract

X-ray emission from the vicinity of the MeV gamma ray source, gamma 195+5, was observed with the HEAO-A2 detectors. A source with an intensity of (1.5 + pr - 0.5) x 10 to the -11th power erg/sq cm s (2-6 keV) was seen in each of two separate observations at a combined confidence level of 3.1 sigma. The location of the source is l2 = 194.56 degrees, b2 = 4.92 degrees with a 90% confidence error box of 1.4 square degrees, significantly smaller than the positional uncertainty of the gamma ray source, and consistent with its location. The chance overlap of such an X-ray source with the gamma ray region is estimated to be 9% and, therefore, they may be 9% and therefore they may be associated. The spectrum appears too steep to extrapolate simply to the 100 MeV flux value for gamma 195+5.
