The present paper deals with the interactions of 16O and 28Si nuclei with emulsion heavy target nuclei (silver (Ag) and bromine (Br)) at 4.5A GeV/c. The results have been analyzed to identify interesting characteristics of the total disintegration (TD) events produced in these interactions. Events having a number of heavily ionizing particles Nh ≥ 28 have been selected in this study. The integral multiplicity distributions for the disintegrated particles from the target nuclei have been used to separate the inelastic interactions with the free hydrogen (H), the light (CNO), and the heavy (AgBr) nuclei. The average multiplicities of the different secondary particles emitted in these interactions have been compared with the corresponding ones of different projectiles nearly at the same momentum. The average multiplicity of the grey particles is found to increase with the mass of the projectile, while the average multiplicity of the black particles is found to decrease with increasing mass of the projectile; this result agrees with the prediction of the fireball model. Also, the dependence of the shower, grey, and black particles produced in the TD events on the mass of the projectile has been studied. Moreover, the dependence of the probability of the TD for the projectile mass as well as the target fragments has also been discussed. The results show that the multiplicity distributions of the shower, grey, and black particles present a Gaussian distribution. Finally, the linear dependence of the grey and compound multiplicities on the black, heavy, and shower particles has also been observed.

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
