Study of Target Dependence of Clan Model Parameter in 84^Kr_36 - Emulsion Interactions at 1 GeV per nucleon

摘要

The article focuses on study of clan model parameters and their targetdependence in light of void probability scaling for heavy (Ag and Br) and light(C, N and O) groups of targets present in nuclear emulsion detector using 84 Kr36 at around 1 A GeV. The variation of scaled rapidity gap (rap gap)probability with single moment combination has been studied. We found thatexperimental points are lying approximately on the negative binomialdistribution (NBD) curve, indicating a scaling behavior. The average clanmultiplicities for interactions, increases with the pseudo-rapidity intervalwas also observed. The values of average multiplicity for AgBr targets arelarger than those for CNO target and also average number of particles per clanincreases with increase in pseudo-rapidity interval. We further observed thatfor a particular target, average number of particles per clan increases with anincrease in the size of projectile nucleus.
