Deep spallation cross sections in high energy protons ? Uranium interactions

Abstract

Cross sections of deep spallation products -from phosphorus to hafnium formed in uranium by high energy protons (Ep> 10 GeV) have been calculated with a simple semi-empirical formula. The results are in excellent agreement with experimental data.

Determination of Gross Sections for the Production of 7Be, 10Be and 22Na by High-Energy Protons

“…It will be highly desirable to evaluate the capabilities of semiempirical formulae using the new data for the determination of the parameter of these formulae, in order to get rid of the bias of unreliable data in such an approach. This will be soon done for the newer formulae [43,44].…”

“…As pointed out above there is no adequate model describing proton-induced high-energy reactions. Several attempts have been made to describe the cross sections of high-energy reactions by semiempirical formulae [41,42,43,44]. The formulae by Rudstam [41] and Silberberg and Tsao [42] tumed out to be widely unreliable and only to represent the general trends of high-energy cross sections.…”
