From a sample of 896 La + Emulsion interactions, 128 events have been selected for the study of the bounce-off phenomenon. These events correspond to non-central and non-peripheral mode of La + Ag(Br) collision. The back to back correlation in azimuthal plane shows strength of the effect in between the 84 Kr + Ag(Br) and 238 U + Ag(Br) collisions. It is further revealend that the projectile fragments (Z ≥ 3) and alphas (Z = 2) show the same strength of bounce-off their emission characteristics are different. This may throw light on the equilibration of two different zones during flow after the collective stage of bounce-off.

STUDY OF CLUSTERS AND HEAVY CLUSTERS IN α-EMULSION INTERACTIONS AT 12A GEV/C

International Journal of Modern Physics A (1989)

V.S. Shukla K.B. Bhalla A. Gill V. Kumar S. Lokanathan

The rapidity gap distributions observed in α-emulsion interactions at 12A GeV/c are analyzed to investigate the variation of cluster size with respect to the size of target nuclei and multiplicity of shower particles (n s ) produced. It is observed that the cluster size increases with the increase in size of the target and with the increase in n s . We also observe rather weak indication of the production of heavy clusters using the method of Adamovich et al.

RAPIDITY DISPERSION AND CLUSTER SIZE DETERMINATION IN α-EMULSION INTERACTIONS AT 12A GeV/c

Modern Physics Letters A (1988)

V.S. Shukla K.B. Bhalla A. Gill V. Kumar S. Lokanathan

The α-emulsion interactions at 12 A GeV /c have been analyzed in terms of the distributions of rapidity dispersion and rapidity gap. Event-by-event analysis of rapidity dispersion reveals a significant clusterization amongst the final state particles. The cluster size and cluster density in rapidity space are estimated to be 5.80 and 0.71, respectively. From the comparison of present results with earlier data, it appears that the cluster size is independent of the nature of projectile and energy.

Freeze-Out Parameters in Central158AGeVP208b+P

Physical Review Letters (1999)

MM Aggarwal A. Agnihotri Z. Ahammed A. L. S. Angelis V. Antonenko

Neutral pion production in central 158AGeV Pb+Pb collisions has been studied in the WA98 experiment at the CERN SPS. The pi0 transverse mass spectrum has been analyzed in terms of a thermal model with hydrodynamic expansion. The high accuracy and large kinematic coverage of the measurement allow to limit previously noted ambiguities in the extracted freeze-out parameters. The results are shown to be sensitive to the shape of the velocity distribution at freeze-out.
