Target dependence of clan model parameter in 84 Kr 36 – Emulsion interactions at 1 GeV per nucleon

Abstract

Abstract. The article focuses on study of clan model parameters and their target dependence 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 Kr 36 at ~1 A GeV. The variation of scaled rapiditygap (rap-gap) probability with single moment combination has been studied. We found that experimental points are lying approximately on the negative binomial distribution (NBD) curve, indicating a scaling behavior. The average clan multiplicities ( ) for interactions, increases with the pseudo-rapidity interval (∆η) was also observed. The values of for AgBr targets are larger than those for CNO target and also average number of particles per clan ( ) increases with increase in pseudo-rapidity interval. We further observed that for a particular target, average number of particles per clan ( ) increases with an increase in the size of projectile nucleus.
