摘要: Abstract Internal pairs produced by π−-mesons captured in hydrogen have been studied with a bubble chamber. The probability that stopped meson produces pair was found to be 0.0093 ± 0.0006. This probability, which is very insensitive the Panofsky ratio, serves check theoretically predicted values of conversion coefficients Joseph.
