We have investigated two-pion normalised pseudorapidity correlation for pions from ¹²C-emulsion interactions at 4.5 A GeV at azimuthal angles f Ł 180^° and f > 180^°. By comparing experimental correlation values with those of Monte-Carlo simulation values, we found that experimental two-pion normalised pseudorapidity correlations depend on azimuthal angle.
