Interference in the c.m.s. of ..pi../sup + -/..pi../sup + -/ pairs produced in ..pi../sup -/p interactions at 40 GeV/c is studied. The size of the region of emission of ..pi../sup -/..pi../sup -/ and ..pi../sup +/..pi../sup +/ pairs turns out to be different, which may be due to the different mechanisms of production of ..pi../sup -/ and ..pi../sup +/ mesons. The interference of pions in the effective-mass region of the rho/sup 0/ meson and outside this region is studied. It is shown that ..pi../sup -/ mesons produced in decay of rho/sup 0/ mesons are emitted from greater distances than the remaining pions.
