Abstract：
The pseudorapidity distributions for charged particle multiplicities 8-12 produced in pp collisions at 400 GeV/ chave been measured by using the LEBC films offered by CERN NA27 collaboration. The c.m.s. forward hemisphere multiplicity distributions at fixed total multiplicities have been analyzed by using cluster model. The results show that the average cluster size is related to whether the leading-particle effect is taken into account.
