Av. Chernyshev et al., A METHOD FOR IMPROVING THE CONSTRAINT ON THE TENSOR COUPLING-CONSTANTIN RADIATIVE PION DECAY, Modern physics letters A, 12(23), 1997, pp. 1669-1676
The possibility exists for improving the present experimental constrai
nt on the tensor coupling constant in radiative pion decay by at least
a factor of six. The method emphasizes relative decay probabilities r
ather than absolute rates.
