ON THE ANNIHILATION OF $mu$$sup +$$-$$mu$$sup -$ AND NEUTRAL MESON DECAY (in Russian)
Aalogous to e/sup +/ -- e/sup -/ annihilation, it may be expected that pi /sup +/ -- mu /sup -/ in a pair state should preduce two quanta and in the ortho-state three quanta. By observing a reverse process, it was found that along with the mu /sup +/ - mu /sup -/ annihilation with quantum emission, it is also possible to convert the mu /sup +/ -- mu /sup -/ pair into an e/sup +/ -- e/ sup -/ p air. The latter process follows the same order of e/sup 2//hc as the two-quantum annihilation. The conversion of ortho mu /sup +/ -- mu /sup -/ into e/sup +/ -- e/sup -/ is about 400 times as probable as the three-quantum annihilation. The pseudo-scalar neutral meson pi /sup 0/ is similar to the pair state; the pi meson decay into two quanta agrees with the annlogy. The neutral odd meson with spin 1 would also be similar to the ortho-state pair; hence such mesons would decay not into three quanta but directiy into e/sup +/ -- e/sup -/ pairs with lifetimes of pi /sup 0/. However, there is small chance for observing pi producing e/sup +/ -- e/sup -/ due to the predominant probability of conversion into 2 pi /sup 0/. (R.V.J.)
