The Comparison of (n,p), (n,α), (n,2n) and (α,n) Reaction Cross-Sections for 7Li and 9Be Target Nuclei

Abstract

The knowledge of the cross-section is important especially for the fusion and fission reactor technology. In the absence of experimental data or in the difficulty of measuring data, theoretical predictions of nuclear crosssection data are needed to be improved using model calculations or semi-empirical formulas and to be compared with model and formulas to obtain sensitive approaches. In this work, for 7 Li and 9 Be target nuclei used as blanket materials in fusion reactors, (n,p), (n,a), (n,2n) and (a,n) reaction cross-section data have been evaluated by using some available empirical and semi-empirical cross-section formulas. The (n,p), (n,a), (n,2n) and (a,n) reaction crosssection formulas developed for medium and heavy mass nuclei by some scientist in literature are applied to 7 Li and 9 Be light nuclei and then results obtained from any systematics are compared with each other and the existing experimental data.

Investigation of 54Fe(α, n)57Ni Reaction for Low Activation Material Fe

“…The experimental measurements model theory calculations and systematic forecast are rather useful to provide this information, particularly for predicting the cross-sections of nuclear reaction [3]. Therefore, recently 54 Fe(, n) 57 Ni crosssections are measured by several authors [4][5][6][7].…”
