摘要：

Within a relativistic quark model predictions for form factors of ω→πγ, a1→πγ, a2→πγ, b1→πγ transitions at 0 ≤|K2|≤ 3 GeV2 are made, which turned out to be significantly different from each other and from VDM predictions. The contributions of these form factors to the cross sections of ω, a1, a2, b1 meson electroproduction via one-pion exchange are found and it is shown that their K2 dependence is quite different for these mesons which is of great interest for experimental research. © 1990.
