摘要：

Measurements of grain densities of stopping π+ and π- mesons in emulsion show that, in the velocity interval 0.051<β<0.178, the energy-loss rates of π+ mesons exceed that of the π- by amounts of 0 to 60 MeV/cm. The reported range differences between positive and negative particles are satisfactorily accounted for by the results of this experiment. © 1969 The American Physical Society.
