Abstract：
A new characteristic quantity called relative information entropy R is introduced,which is employed to investigate the multiplicity distribution of produced particles in 14.6. 60, 200 A GeV oxygen ions and 200 A GeV sulphur ions induced nuclear reactions. It is found that R is insensitive to energy. R increases with the size of rapidity window and rapidly reaches saturation, which explores the fact that the entropy is concentrated in the central rapidity region. The experimental results are in good agreement with the prediction of the FRITIOF simulation of the Lund model.
