The interaction of 400 GeV/c protons and 340 GeV/c π- with nucleons in nuclear emulsion has been investigated. The interaction mean free paths (m.f.p.) and the corresponding reaction cross-sections (σ in ) have been found, the multiplicity distributions for the events with Nh = 0 (clean events) are measured and studied as well as the angular and pseudorapidity distributions. Finally the coherent multiparticle production cross-sections (σ coh ) were estimated and compared with other data, where it was found to be increasing slowly with increasing incident momentum for protons while it increases rapidly with increasing π--momentum.

Heavy Hadron

A production mechanism of heavy particles in e+e− annihilations is studied on a field theoretical basis using the bound state wave functions. The requirement that wave functions of hadrons overlap maximally with each other leads to the conclusion that (1) the model predicts a 2-jet structure in a one-loop diagram and (2) heavy hadrons in a jet have an equal velocity. Heavy particle production cross sections and their characteristic energy distributions are calculated for some typical reactions.

The Cross

The projectile fragment separator type radioactive ion beam (RIB) facilities, being developed in different laboratories, provide the scope for producing many new exotic nuclei through fragmentation of high energy radioactive ion (RI) beams. A new empirical parametrization for the estimation of cross-sections of projectile fragments has been prescribed for studying the advantages and limitations of high energy RI beams for the production of new exotic nuclei. The parametrization reproduces the experimental data for the production of fragments from neutron-rich projectiles accurately in contrast to the existing parametrization which tends to overestimate the cross-section of neutron-rich fragments in most cases. The modified formalism has been used to compute the cross-sections of neutron-rich species produced by fragmentation of radioactive projectiles (RIBs). It has been found that, given any limit of production cross-section, the exoticity of the fragment increases rather slowly and shows a saturation tendency as the projectile is made more and more exotic. This essentially limits, to an extent, the utility of very neutron-rich radioactive beams vis-a-vis production of new neutron-rich exotic species.

In this work, we present the study of emissions of light fragments produced in interactions of 160 GeV muons with emulsion nuclei. A total of 820 interactions with emulsion nuclei were collected. Thickness, coordinate and range of each track were measured. Charges of emitted fragments were identified and the corresponding energies were calculated. Multiplicity, total particle production cross-sections and angular distribution of particles (P, He, Li, Be and B) were presented. Forward–backward–angular correlations were measured for the emitted alpha particles. Short and long range correlation among pairs of Alfa particles were observed at specific angular intervals. The experimental data and the results of the angular correlation were used to find the probable mechanism of producing alpha particles and to reveal the dynamic characteristics of the reactions.
