Abstract

In a preliminary version of the NA48 experiment at the CERN SPS, in which an iron-scintillator sandwich calorimeter was used as a photon detector, the ratio of K-L --> pi mu nu gamma and K-L --> pi mu nu decays was measured. The branching ratio BR(K-L --> pi mu nu gamma,E-gamma*greater than or equal to 30 MeV)/(K-L --> pi mu nu) is found to be (2.08+/-0.17(-0.21)(+0.16)x10(-3), where the first error is statistical and the second systematic. The result is in agreement with theoretical predictions.
