摘要：
We have measured the nucleon-number (A) dependence of hadron-pair production in 400-GeV/c proton-nucleus collisions, using Pb and Be targets. Charged-hadron pairs were observed near rapidity yc.m.=-0.4 with Δ≅180°. The A-dependence exponent rises from 1.1 to 1.2 in the range 2.0<|p1|+|p2|<4.5 GeV/c. The dihadron p correlation function is significantly smaller for Pb than for Be. © 1979 The American Physical Society.
