The COMPASS Collaboration at CERN has investigated the reaction embedded in the Primakoff reaction of 190 GeV pions scattering in the Coulomb field of a lead target. Exchange of quasi-real photons is selected by isolating the sharp Coulomb peak observed at momentum transfer below 0.001 (GeV/c)(2). Using a partial-wave analysis the amplitudes and relative phases of the a(2)(1320) and (pi2)(1670) mesons have been extracted, and the Coulomb and the diffractive contributions have been disentangled. Measuring absolute production cross sections we have determined the radiative width of the a(2)(1320) and of the (pi2)(1670). We compare these values to previous measurements and theoretical predictions.
