Description

We have constructed semiempirical equations for calculating the total inelastic cross sections in nucleus-nucleus (N-N) collisions. To a first approximation, the magnitudes of partial breakup cross sections (for products heavier than hydrogen) are proportional to those of the corresponding proton-nucleus (p-N) interactions. However, the proportionality factor is different from the ratio of total inelastic cross sections: nuclei like C and O more frequently undergo complete breakup in collisions with complex nuclei than with protons.

Abstract (German)

Es wurden halbempirische Gleichungen zur Berechnung der totalen unelastischen Wirkungsquerschnitte bei Kern-Kern-(N-N) Kollisionen aufgestellt. In erster Naeherung ist der Wert der partiellen Breakup-Querschnitte (fuer Reaktionsprodukte schwerer als Wasserstoff) proportional zu dem fuer die entsprechenden Proton-Kern-(p-N)-Wechselwirkungen. Der Proportionalitaetsfaktor ist jedoch verschieden vom Verhaeltnis der totalen unelastischen Wirkungsquerschnitte: Kerne wie C und O brechen bei Reaktionen mit komplexen Kernen haeufiger vollstaendig auseinander als bei solchen mit Protonen.
