Cross-Section Calculations of (γ,xn) and (p,xn) Reactions for 197Au

In this study, cross–sections of (γ,n), (γ,2n), (γ,3n) and (p,xn) reactions for 197 Au have been calculated. The main aim of this study is to investigate the pre–equilibrium and equilibrium effects on 197 Au. While the Weisskopf–Ewing and equilibrium models have been used for the equilibrium process in the calculations, the hybrid, geometry dependent hybrid and two component exciton nuclear reaction models have been used for the pre–equilibrium process. For this purpose, the TALYS 1.6, EMPIRE 3.2 and ALICE/ASH codes have been used. The calculated results have been discussed and compared with the experimental data. Keywords : 197 Au, Cross Section, TALYS 1.6, EMPIRE 3.2. Ozet:  Bu calismada, 197 Au icin (γ,n), (γ,2n), (γ,3n) ve (p,xn) reaksiyonlarinin tesir kesitleri hesaplanmistir. Bu calismanin ana amaci, 197 Au uzerindeki denge oncesi ve denge etkilerinin incelenmesidir. Denge hesaplamalari icin Weisskopf-Ewing ve denge modelleri kullanilirken, denge oncesi hesaplamalari icin hibrid, geometri bagimli hibrit ve iki bilesenli eksiton model kullanilmistir. Bu amacla, TALYS 1.6, EMPIRE 3.2 ve ALICE/ASH kodlari kullanilmistir. Hesaplanan degerler, teorik veriler ile kiyaslanmistir. Anahtar kelimeler : 197 Au, Tesir Kesiti, TALYS 1.6, EMPIRE 3.2.
