英文摘要	We searched for steady PeV gamma-ray emission from the Monogem ring region with the Tibet air shower array from 1997 February to 2004 October. No evidence for statistically significant gamma-ray signals was found in a region 111 degrees <= R.A. < 114 degrees, 12 degrees.5 <= decl. < 15 degrees.5 in the Monogem ring where the MAKET-ANI experiment recently claimed a positive detection of PeV high-energy cosmic radiation, although our flux sensitivity is approximately 10 times better than MAKET-ANI's. We set the most stringent integral flux upper limit at a 99% confidence level of 4.0 x 10(-12) cm(-2) s(-1) sr(-1) above 1 PeV on diffuse gamma rays extended in the 3 degrees x 3 degrees region.
