Abstract
- We report the first inclusive photon measurements about mid-rapidity (|y| photon photon decay channel. The fractional contribution of the pi0 -> photon photon decay to the inclusive photon spectrum decreases by 20% +/- 5% between pt = 1.65 GeV/c and pt = 2.4 GeV/c in the most central events, indicating that relative to pi0 -> photon photon decay the contribution of other photon sources is substantially increasing.<br />13 pages, 14 figures, submitted to Phys.
