New method for determination of temperature in spallation reactions

We propose a new method for determination of temperature in spallation events. It is shown that temperature can be determined by applying the friction model of energy dissipation in participant-spectator model of a spallation process. First order estimate of temperature dependence of the participant zone on reaction Q-value is obtained from the Fermi gas model considerations. The heat diffusion process is also discussed. Prikazana je nova metoda odredjivanja temperature u spalacionim dogadjajima. Pokazano je da temperatura moze biti odredjena primenom frikcionog modela energije disipacije na participant-spektator modelu spalacionih procesa. Prva procena zavisnosti temperature participant zone od reakcione Q-vrednosti dobijena je primenom Fermi gas modela. Razmatran je i proces toplotne difuzije.
