C. H. M. Broeders
Abstract
An extensive analysis of the accuracy in the theoretical reproduction of experimental proton induced reaction cross-sections up to 150 MeV is presented. The predictive capabilities of different models for the description of the nuclear level densities as implemented in the TALYS code and in the modified ALICE code have been assessed by means of a systematic comparison of the theoretical results with experimental EXFOR data relative to target nuclei from 24Mg to 209Bi. The results obtained give the possibility to find the best approaches for the cross-section calculation for nuclei from different mass ranges and for different channels.
Kurzfassung
Die extensive Analyse der Vollständigkeit in der theoretischen Reproduktion der experimentellen Wirkungsquerschnitte fuer Reaktionen induzierte durch Protonen mit einer Energie bis zu 150 MeV wird dargestellt. Die prädiktive Fähigkeit der verschiedenen Modellen fuer die Beschreibung die Kernniveaudichte verwendet in TALYS and ALICE/ASH Codes ist für Targets von 24Mg bis 209Bi festgesetzt. Die erhaltene Ergebnisse geben die Möglichkeit die besten Annäherungen für die Berechnung der Wirkungquerschnitten für Kerne der unterschiedlichen Massen zu finden.
