摘要
A new concept,rigidity of pseudo-rapidity spectrum,is extended into the study of the multiplicity fluctuations in high energy nucleus-nucleus interactions.In using the novel method to analyze the data of l6O-Em at 14.6,60,and 200A GeV,and ^(32)S-Em at 200A GeV,it is found that the rigidity of pseudo-rapidity spectrum in the central domain of pseudo-rapidity might be a mixture of Poisson type and Wigner one.
