摘要：

It is shown that π→evγ decay is sensitive to the search for a tensor coupling in the effective quark-lepton four-fermion interaction. The experimental data from the ISTRA facility may be interpreted as an indication for a nonzero tensor coupling |φT|≅4×10-2. The value obtained does not contradict the listed constraints on this coupling. © 1990.
