Özet

Coherent pi (+)pi (-)pi (-) production in the interactions of a beam of 600GeV pi (-) mesons with C, Cu and Pb nuclei has been studied with the SELEX facility (Experiment E781 at Fermilab). The a(2)(1320) meson signal has been detected in the Coulomb (low q(2)) region. The Primakoff formalism used to extract radiative decay width of this meson yields Gamma = 284 +/- 25 +/- 25 keV, which is the most precise measurement to date. (C) 2001 Elsevier Science B.V.
