A few analytical results are presented for the bunching parameters analysis applied to study the fluctuations of hadron multiplicity density in high energy collisions. The behaviors of bunching parameters are analyzed in the cases of concatenate and partitioning fluctuations. The effect of pairing in partition is also studied. As the phase-space decreases, the concatenation can be observed as the divergence of one of the bunching parameters, which also implies a strong short range correlation. In the case of a weak short range correlation, both types of binomial partitions lead to saturation for all the bunching parameters. As the phase-space increases, the effects of pair production can be observed as the oscillatory bunching parameters ηq — a function of order q. The characteristics of the observed features are discussed. Comparisons to experimental data are also presented.

The effect of short range correlations on the inelastic longitudinalCoulomb form factors for different states of J   4 , T  1withexcitation energies 3.553,7.114, 8.960 and 10.310 MeV in 18O isanalyzed. This effect (which depends on the correlation parameter )is inserted into the ground state charge density distribution throughthe Jastrow type correlation function. The single particle harmonicoscillator wave function is used with an oscillator size parameter b.The parameters  and b are considered as free parameters, adjustedfor each excited state separately so as to reproduce the experimentalroot mean square charge radius of 18O. The model space of 18O doesnot contribute to the transition charge density. As a result, theinelastic Coulomb form factors of 18O comes absolutely from thecore polarization transition charge density. According to thecollective modes of nuclei, the core polarization transition chargedensity is assumed to have the form of Tassie shape. It is found thatthe introduction of the effect of short range correlations is necessaryfor obtaining a remarkable modification in the calculated inelasticlongitudinal Coulomb form factors and considered as an essential forexplanation the data amazingly throughout the whole range ofconsidered momentum transfer.
