Total prompt muon production rate for muons with Plab>8 GeV has been measured in 350-GeV p-Fe collisions. A prompt rate of (3.29±0.45)×10-4 per collision is determined, yielding μ/π=(0.93±0.13)×10-4. The μ/π ratio does not show the rise at small XF and small PT seen in intersecting-storage-ring electron/π measurements. A charm production cross section of 22±9 μb/nucleon is extracted from the contributions of prompt single muons to the total prompt rate.
