Abstract
The space--time characteristics of the generation of charged pions in ..pi../sup -/ /sup 12/C interactions at 5 GeV/c is investigated. The obtained dimensions of the interaction region and of the pion emission time are R=2.9 +- 0.08 F and tau= (7.4 +- 3.5) x 10/sup -24/ sec. These results agree with the data at 3.7 and 40 GeV/c.
