Single-Particle Correlations In Events With Total Disintegration Of Nuclei

New experimental data on the behavior of the single-particle two-dimensional correlation functions R versus Q (Q is the number of nucleons emitted from nuclei) and A(p) (A(p) is the mass of projectile-nuclei) are presented. The interactions: of protons, d, He-4, and C-12 nuclei with carbon nuclei (ata momentum of 4.2 A GeV/c) are considered. The values of R are obtained separately for pi(-) mesons and protons.ln so doing, the values of R are normalized so that -1 less than or equal to R less than or equal to 1. The value of R = 0 corresponds to the case of the absence of correlations. It has been found that the Q and A(p) dependence of R takes place only for weak correlations (R<0.3). In the main (90%), these correlations are connected with the variable p(t) and have a nonlinear character; that is, the regions with different characters of the Q dependence of R are separated: there is a change of regimes in the Q dependences of R. The correlations weaken with increasing A,, and the variable R gets the lowest values of all the ones considered in (CC)-C-12 interactions. Simultaneously with weakening the correlations in the region of large Q, the character of the Q dependence of R changes.
