摘要：

The relative yields on three different targets for the inclusive production of two π- are fitted to σ ∼ Aα for proton-nucleus interaction at plab = 28.5 GeV/c at different transverse pion momenta. The exponent α increases with pT and becomes greater than 1 at pT > 1.1 GeV/c. The data are compared with fireball models to determine the lifetime τ and dimension R of the fireball. For beryllium, we found τ = (1.4-0.6+0.5) × 10-24 sec and R = 0.8 ± 0.4 fm. © 1979.
