Equilibrium, Isoscaling and Nuclear Isotope Thermometry Related to 1 Gev Proton Induced Reactions

Experimental data, related to the decay modes of systems produced in 1 GeV protonnucleus interactions, have been analysed by methods probed in nucleus-nucleus collisions. The actual questions are addressed to the next topics: attainment of equilibrium in fragmenting systems [1], isoscaling [2] and nuclear isotope thermometry [3, 4]. With this intention we have investigated: • reactions with cumulative production of Light Charged Particles (LCP) • emission of Intermediate Mass Fragments (IMF) in fragmentation processes • production of residual nuclei in spallation reactions The present paper is a review of recent publications [5, 6, 7] based on experimental results from [8, 9, 10, 11]. Especially, the earlier and precise data [9] are suited for a comprehensive analysis. Fragment production in proton collisions with light target nuclei [10] allows to test the above mentioned questions including small nuclear systems.
