“…The investigation of particle-nucleus collisions is fundamental for understanding the nature of the interaction process and these collisions have been studied extensively [1][2][3][4][5][6]. In experiments on hadron-nucleus (hA) collisions, mostly the attention was paid to the studies of relativistic charged particles produced during these reactions; however, less attempt was made to study the grey and black particles.…”

We report some results on the compound multiplicity distribution at 340 GeV/c − nucleus interactions. Compound multiplicity distribution is found to depend on the target size and the distribution becomes broader. The peak of the distribution shifts towards higher values of the compound particle multiplicity. Mean compound multiplicity is found to vary linearly with grey, heavy, and shower particle multiplicity. Correlations between different particle multiplicities have been studied in detail. Dispersion of compound multiplicity distributions and its ratio with the mean value is observed to obey a linear relationship with different particle multiplicities except for shower particles where dispersion is almost independent of shower particles. Mean normalized multiplicity has also been studied in terms of created charged particles.

“…Shower tracks are relativistic charged particles whereas grey and black tracks are slow particles. The other details regarding the size of the plates, flux and the total number of interactions in the data sample are given in our earlier publications [4][5][6][7].…”

“…The high energy hadron-nucleus (hA) collisions have been studied by several workers [1][2][3][4][5][6][7]. An important feature noticed in these interactions is that the nucleus plays the role of the target for the incident hadron as well as the newly produced hadronic systems.…”

A detailed study on mean multiplicities of secondary charged particles is presented. The average number of grey, black and heavy particles are found to be independent of energy in proton-nucleus interactions whereas for pion-nucleus collisions the data deviates from its independence with energy. The ratio of mean number of charged particles produced in pion-nucleus collisions to its number in proton-nucleus interactions at almost the same energy is found to be similar at different energies.

“…The backward emission of protons and pions in hadron-nucleus [1][2][3][4][5][6][7] and nucleus-nucleus [8][9][10][11][12][13][14][15][16][17][18] at relativistic energies have been investigated exclusively. It is found that the backward proton production was attributed to the absorption of secondary pions by a nucleon pair in the target nucleus, and the backward pions production shown to be consistent with the cumulative effect [19].…”

The forward-backward multiplicity and correlations of target evaporated fragment(black track particle) and target recoiled proton(grey track particle) emitted in 150 A MeV 4 Heemulsion, 290 A MeV 12 C-emulsion, 400 A MeV 12 C-emulsion, 400 A MeV 20 Ne-emulsion and 500 A MeV 56 Fe-emulsion interactions are investigated. It is found that the forward and backward averaged multiplicity of grey, black and heavily ionized track particle increase with the increase of target size. Averaged multiplicity of forward black track particle, backward black track particle, and backward grey track particle do not depend on the projectile size and energy, but the averaged multiplicity of forward grey track particle increases with increase of projectile size and energy. The backward grey track particle multiplicity distribution follows an exponential decay law and the decay constant decreases with increase of target size. The backward-forward multiplicity correlations follow linear law which is independent of the projectile size and energy, and the saturation effect is observed in some heavy target data sets.
