Abstract:
Local characters of finite state multiplicity spectra in high energy 16O-induced nuclear emulsion(Em)and 32S-induced gold nuclei(~197Au)violent central collisions are investigated systematically.Both the dependences of dispersion on mean value、incident energy and centrality and factorial moment F2 on energy and centrality are given out.The validity of parametrizations of multiplicity spectra in local rapidity windows are examined.The dependence of normalized variance on window are analyzed and the estimation of the number of particle emitting source is discussed.
