Descripción
Sumario:Experimental data, recently measured at CERN, on the LPM effect have been used to benchmark the description of the discrete bremsstrahlung incorporated into the GEANT 3 and GEANT 4 codes. The limited accuracy of the native versions required a major revision in the framework of the original Migdal theory. The results obtained with the new implementation agree quite satisfactorily with measurements. The stability of the calculations when several parameters are varied has been thoroughly investigated.
