用γ-γ符合方法测量了停在氢中的负π介子的二个俘获过程的几率比。实验结果等于1.40±0.08。这个数值和利用光生π介子反应和π介子-核子散射数据推出的值是符合的。The ratio of the probability of two capture processes of stopped negative pions in hydrogen was measured by the γ-γ coincidence method. The experimental result is equal to 1.40 ±0.08. This value agrees with the datum on photoproduction and scattering of pions.
