The interactions of 4.5 A GeV/c 24Mg and 32S nuclei with emulsion were studied. The experimental inelastic mean free path for these interactions is compared with theoretically calculated values. The average multiplicities of the emitted secondary charged particles for total disintegration were investigated. Total disintegration events are analysed to investigate the characteristics of secondary charged particles produced in such collisions. The results show that the multiplicity distributions of relativistic charged particles agree with the Gaussion distribution. The average multiplicity of grey and black particles is in good agreement with the prediction of the fireball model. The probabilty of total disintegration of Ag(Br) nuclei by different projectiles is nearly independent of the incident energy. PACS No.: 25.70

Total disintegration events produced in 4.5 A GeV/c 12C--AgBr reactions are analysed to investigate the characteristics of secondary charged particles produced in such collisions. The results reveal that multiplicity distributions of grey, black, and relativistic charged particles agree with the Poisson distribution. The average multiplicity of grey particles is found to increase with the increasing mass of projectile, while the average value of black particles is found to decrease with the increasing mass of projectile. This result is in good agreement with the prediction of fireball model. Finally, the linear dependence of grey and compound multiplicities on black, heavy, and relativistic charged particles is also observed. PACS No.: 25.70

Energy Loss Function (ELF) of 2 5 Ta O derived from optical limitand extended to the total part of momentum and their energyexcitation region ELF plays an important function in calculatingenergy loss of electron in materials. The parameter Inelastic MeanFree Path (IMFP) is most important in quantitative surface sensitiveelectron spectroscopies, defined as the average distance that anelectron with a given energy travels between successive inelasticcollisions. The stopping cross section and single differential crosssectionSDCS are also calculated and gives good agreement withprevious work.

The common experimental method to determine the total inelastic mean free path i by electron energy-loss spectroscopy (EELS) is by the relation : t/λi= ln(It/IO) [1] where t is the specimen thickness, It, is the total integrated intensity, and Io is the intensity of the zero-loss peak. The accuracy of this measurement depends on the thickness determination. Model geometries like cubes, wedges, and spheres enable accurate thickness determination from transmission images.Spherical polymers with diameters of order 10-200nm can be made from a number of high-Tg polymers by solvent atomization. This research studied atomized spheres of poly(2-vinyl pyridine) [PVP]. A solution of 0.1% PVP in THF was nebulized. After solvent evaporation during free fall within the chamber atmosphere, solid spherical polymer particles with a range of diameters were collected on holey-carbon TEM grids at the bottom of the atomization chamber.
