The photographic emulsion is one of several means of detecting charged particles emitted in nuclear reactions or from radioactive materials, and emulsion technique has developed enormously over the past few years; it is now an invaluable laboratory tool. Whilst the principles of nuclear emulsion microscopy are well established, the application of interference microscopy to the study of nuclear emulsions is new. Although it seems that the interferometric technique would have no real advantage at the present time over the conventional microscopic methods of track examination, it is felt desirable to report some observations on the examination of tracks by interferometry and to suggest some lines of possible investigation.

The experimental results on the multiplicity and probability distribution of the emitted charged pions [Formula: see text] in the interactions of [Formula: see text]Kr[Formula: see text] projectile at around 1[Formula: see text]GeV per nucleon with nuclear emulsion targets are reported. In this work, we have employed a wounded nucleon model (WNM) to calculate the total number of wounded nucleons [Formula: see text] and the total number of interactions [Formula: see text]. The dependence of average multiplicities of produced relativistic charged particles on the calculated wounded nucleons and total interactions are investigated. The obtained results revealed that the average multiplicity of [Formula: see text] is dependent on the projectile and target mass number. The calculated values of the total number of wounded nucleons and the total numbers of interactions show a strong dependence on the mass of the colliding nuclei. The emission rate of the mean multiplicity of [Formula: see text] and [Formula: see text] linearly increases with increasing the total number of wounded nucleons and interactions.

This work displays a study of the compound multiplicity characteristics of 4.1 A GeV/c 22Ne–emulsion interactions, where the number of shower and grey particles taken together is termed as compound multiplicity, Nc. The present data are compared with the corresponding ones obtained for other projectiles at nearly the same momentum per nucleon. It is observed that while the average compound multiplicity depends on the mass number of the projectile, Ap, the value of the ratio <Nc>/D(Nc) seems to be independent of Ap. The impact parameter is found to affect the shape of the compound multiplicity distribution. A positive linear dependence of the compound multiplicity on both the black and heavy charged particles is also noted. Finally, the results indicate that the value of <Nc> depends also on the target mass number. PACS No.: 25.70

Dependence of cluster size on relativistic charged particle multiplicity is examined by analyzing experimental data involving 530 and 283 interactions with nh≥0 caused by 4.5 A and 14.5 A GeV/c28 Si –beams in nuclear emulsion. The results reveal that the maximum number of charged particles constituting a cluster is four for the collisions having ns≥10, where ns is the number of relativistic charged particles produced in interactions with relative velocity β≥0.7. However, this number is found to be three for the interactions having ns≤9. Results also show that the cluster size is essentially insensitive to the projectile energy.

Pseudorapidity density distributions of relativistic charged particles produced in 28 Si -induced interactions in nuclear emulsion at JINR Synchrophasotron have been measured. The particle distributions in minimum-bias events exhibit a pronounced forward asymmetry with respect to the peak in the pseudorapidity spectra. The effect of intranuclear collisions on the mean pseudorapidity distribution versus the shower particles (ns) or the grey particles is discussed and compared with similar studies of 28 Si and 32 S at BNL AGS and CERN SPS energies respectively.

The paper presents new data on azimuthal correlations in angles between different types of secondary charged particles emitted in inelastic interactions between 24Mg nuclei with the AgBr nuclei of nuclear emulsion. Azimuthal correlations are observed in some cases of intergroup correlations, and an asymmetry is found to exist in the emission of the same type of particles. The present data is compared in some cases, with those of p-emulsion, d-emulsion, α-emulsion and 12C-emulsion interactions at 4.5 A GeV/c and 84Kr-emulsion interaction at 1.4 A GeV.
