The absolute number of spurious tridents due to 10/sup 10/ 10/sup 11/, and 10/sup 12/ ev primary electrons is computed by the Monte Carlo method for two types of bremsstrahlung spectrum: for that described by the Bethe-Heitler formula and that described by the Migdal formulas which take into account the Landau- Pomeranchuk and TerMikaelyan effects. It is shown that it should be feasible to measure the energy of fast electrons by determining the energy dependence of the mean transverse distance between the vertexes of electron-positron pairs produced by bremsstrahlung gamma quanta. The value computed by Bhabha for the cross section of direct formation of electron-positron pairs is confirmed experimentally. (auth)
