  We analyze within the light-cone path integral approach [4] the recent CERN
SPS data [19] on the Landau-Pomeranchuk-Migdal effect for photon bremsstrahlung
in quantum regime from 149, 207, and 287 GeV electrons. Calculations have been
carried out treating accurately the Coulomb effects and including the inelastic
processes. Comparison with experiment is performed accounting for multi-photon
emission. Our results are in good agreement with the data.
