Abstract

In the present study, the region of the gamma 195 + 5 was searched for X-ray emission to a level of approximately 10 to the minus eleventh erg/sq cm-sec. A source is detected whose position is in agreement with the position of the gamma-ray source. The area of the X-ray box is approximately five times smaller than the estimated gamma-ray error region; it will guide further observations at X-ray and other wavelengths. The probability that the source is located by chance within the gamma-ray error region is estimated at 9%. The X-ray spectrum appears to be too steep to extrapolate simply toward the 100 MeV point.
