Interactions of {sub 82}Pb{sup 208} nuclei with energy 158 GeV per nucleon with photoemulsion nuclei; Vzaimodejstviya yader {sub 82}Pb{sup 208} s ehnergiej 158 Gev na nuklon s yadrami fotoehmul'sii

Abstract

In this report there are experimental data on {sub 82}Pb{sup 208} nuclei (158 GeV) interaction with photoemulsion nuclei. The said data are compared to the similar ones for {sub 79}Au{sup 197} nuclei with less energy (10,7 A GeV). Stack of nuclear emulsion was irradiated with the beam of nuclei {sub 82}Pb{sup 208} at SPS of CERN. Events search was done along the primary nucleus trace. Pb nucleus average path length happened to be {lambda}=(3,8{+-}0,1) cm, this virtually coincides with the one calculated by Brandt and Peters formula (3,9 cm). Secondary particles were identified into s (storm), g (knock-on protons) and b- particles (target nucleus fragments), as well as into nucleus-bullet fragments with different charges (Z=1,2,{>=}3). This allowed obtaining event distribution by multiplicity of these particles (n{sub s}, n{sub g}, n{sub b}) and fragments (n{sub z=1,2,{>=}}{sub 3}), calculation of average values by multiplicity (see table), finding correlation of characteristics. >From the table it's clear that when the energy increases <n{sub s}> increases 2,5 times where as <n{sub g}> insignificantly decreases and <n{sub b}> doesn't change.
