Experimental data on the two-particle correlation functions R/sup( n)/(y/sub 1/*,y/sub 2/*) and C/sup( n)/(y/sub 1/*, y/sub 2/*) for ..gamma..ch, ..gamma pi../sup -/, ..gamma pi../sup +/, and ..gamma gamma.. systems in semi-inclusive ..pi..-p interactions at 40 GeV/c are presented. It is shown that R/sup( n)/(0, 0) and C/sup( n)/(0, 0) vanish (within two standard errors) for various secondary-charged-particle multiplicities. A particle-identity effect is observed in the azimuthal correlations of ..gamma gamma.. pairs at Phi..-->..0.
