The momentum and angular distributions of punchthrough muons have been measured after a 10 lambda calorimeter using an iron toroid magnet with 1.5 T as spectrometer-The calorimeter was inside a variable magnetic field of 0 to 3 T. The incident momentum of the pi(-) beam ranged from 20 to 300 GeV/c. Measurements were also done at some beam momenta for pi(+) K+ and p. The results are compared with Monte Carlo predictions. A parameterization for the momentum spectrum of punchthrough muons was derived from the data.
