Comparison of the Isolated Direct Photon Cross Sections in $p\bar{p}$ Collisions at $\sqrt{s}=1.8$ TeV and $\sqrt{s}=0.63$ TeV

CDF Collaboration, D. Acosta

We have measured the cross sections $d^2\sigma /d{P}_{T}d\eta$ for production of isolated direct photons in \pbarp collisions at two different center-of-mass energies, 1.8 TeV and 0.63 TeV, us…
