Bombarding Energy

The distributions in angle and energy for charged particles emitted from polycrystalline platinum bombarded with ions of hydrogen, sodium, potassium and some hydrocarbons, have been measured, in continuation of previous work (Cawthron, Cotterell & Oliphant 1969 a , b , parts I and II; 1970, part III) to lower energies. Composite spectra are presented, including ions of both signs. The flux of emitted charged particles, under hydrogen ion bombardment, is shown to contain approximately equal numbers of protons and H¯ ions, except at the lowest bombarding energies, where the latter apparently predominate. Scattering in all cases is shown to increase with bombarding energy over the range covered, the increase being near linear for hydrogen and very rapid for alkalimetal ions. In all cases the total emission of charged particles is very small at the lowest bombarding energies employed.

Fritiof Model

The characteristics of the interactions of 4.5 A GeV/c 28 Si nuclei with emulsion have been investigated. The method of separating interactions into those with hydrogen, light and heavy target nuclei has been discussed. The multiplicity distribution, average multiplicities, multiplicity correlation and the angular distributions of the secondary particles emitted in 28 Si -emulsion are calculated according to the Modified Fritiof Model and compared with the experimental data and with other available data for p, 12 C , 24 Mg at the same energy. It has been found that the modified Fritiof model can describe the multiplicity characteristics of the different emitted particles in the above-mentioned interaction with different target groups. The comparison of the experimental data with the modified Fritiof model shows no clear preference for the case of the light target while it seems to be nearer to the experimental data in the case of the heavy target and the emulsion

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.

Relativistic Particles

An attempt has been made to study the angular characteristic of relativistic charged particles produced in 4.5 A GeV/c 12C-emulsion collisions. The dependence of these characteristics on the multiplicity of the relativistic particles, Ns, has also been investigated. The results reveal that the angular distributions of relativistic particles do not depend on Ns, except at small angles where contribution of singly charged particles fragments enhances the number of relativistic charged particles. It is also observed that the maximum of pseudorapidity, η and <η> distributions, shifts towards the lower value of η with increasing multiplicity of Ns. The study of the rapidity dispersion of relativistic charged particles reveals that the clusterization effect occurs significantly among the final state relativistic particles produced in heavy ion interactions.
