Mean life-time of the neutral pion
The mean lifetime of the rature of the d /sup o/ meson is measured. The decay distance of rature of the d /sup o/ mesons produced by K/sub rature of the d 2/ decay at rest (K/sup +/ min gave no sig rature of the d /sup +/ + rature of the d /sup o/) and subsequent decay by the Dalitz mode(( rature of the d /sup o/ min gave no sig e/sup +/ + e/sup -/ + gamma ) is measured. Using Ilford G-5 emulsio ns, exposed in a 300 Mev/c separated K/sup +/ beam, 88 of the above events are found. The observed mean rature of the d /sup o/ lifetime is (2.8 ction in DDT-C/ 0.9) x 10/sup -16/ sec. (auth)
