Investigation of proton-nuclear reactions on isotopes $^{129}$I, $^{237}$Np and $^{241}$Am at $E_p$ = 660 MeV

Abstract

Cross sections of the residual nuclei production in $^{129}$I, $^{237}$Np and $^{241}$Am target irradiated by proton beam with energy 660 MeV are measured by means of activation analysis with the use of HPGe detectors. The number of product nuclei identified amounts to 74 for $^{129}$I target, 53 for $^{237}$Np target and 80 for $^{241}$Am target. Theoretical model analysis employing eleven contemporary computer models of hadron-nuclear interactions is performed. Insufficient for practical purposes precision of modelling of the reactions under study is demonstrated. Methods for short-lived beta-unstable reaction product identification are developed and amended, a program package for gamma-spectrometry data analysis is described.
