“…In particular, universal features of spectator multifragmentation has been well documented [17,24]. The transverse momentum change of the spectator during a semicentral collision, to be addressed here, was looked at in the past via emulsions by Bogdanov et al [18] (see also [19]). The systematics of the longitudinal momentum transfer to spectators in energetic reactions induced by light projectiles can be found in Ref.…”

The interplay between spectator and participant matter in heavy-ion collisions is investigated in the context of a microscopic transport model. Transport simulations show that flow patterns for the participant matter are strongly influenced by the presence of the nearby spectator matter. However, the influence is mutual. During the explosion of the participant zone, the spectator matter acquires a transverse momentum P x /A that shows sensitivity to the nuclear incompressibility and to the momentum dependence of the nuclear mean field (MF). An observed change in the net average momentum per nucleon, ∆| P/A |, can be associated with the momentum dependence of the MF. For a momentum-dependent MF and a low impact parameter in a heavy system, the spectators may emerge faster than in the initial state, accelerated by the violent participant explosion. The average excitation energy and the mass of the spectators, in contrast to the momentum, show little sensitivity to the nuclear equation of state. 25.70.z, 25.75.Ld, 21.65.+f Typeset using REVT E X

“…Moreover, the probability of all target nuclei to emit alpha particles seems to be remarkably large compared to emitting other fragments. This experimental fact ensures that alphaparticle is a tightly bound structure and a strong possibility that nuclei might be considered as composed of alpha clusters, as supported by several research workers [23][24][25][26][27][28][29].…”

In this work we present some results of the interaction of high energy muons with emulsion nuclei. The interaction results in emission of a number of fragments as a consequence of electromagnetic dissociation of the excited target nuclei. This excitation is attributed to absorption of photons by the target nuclei due to the intense electric field of the very fast incident muon particles. The interactions take place at impact parameters that allows ultra-peripheral collisions to take place, leading to giant resonances and hence multi-fragmentation of emulsion targets. Charge identification, range, energy spectra, angular distribution and topological cross-section of the produced fragments are measured and evaluated.

An attempt has been made to study the multiplicity, angular and pseudo rapidity distributions of relativistic charged particles emerging from the interactions between sulphur and nuclear emulsion nuclei at 200 GeV/nucleon. The distributions from 200 AGeV are compared to the corresponding distributions from the predictions of Monte Carlo code FRITIOF samples. The pseudo rapidity distributions in different Nh-intervals translate to the target fragmentation region with increasing target mass. Finally, the scaling of multiplicity distributions of shower particles successfully describes the consequences of KNO scaling.
