摘要：

We report the results of an experiment made at the CERN ISR to investigate the possible diret production of single photons in pp collisions at √s = 53.2 GeV at 90° and in the pt interval 2.3 to 5.7 GeV/c. The value of the ratio R = nγ/nπ0 is compatible with zero for low pt {less-than or approximate} 3 GeV/c but, in spite of the large error, shows a trend to increase for larger pt. © 1979.
