Abstract

In this study 206Pb(p,2n)205Bi, 206Pb(p,3n)204Bi, 206Pb(p,5n)202Bi, 207Pb(p,2n)206Bi and 207Pb(p,3n)205Bi reaction cross sections have been calculated with TALYS 1.95 code. Geometry Dependent Hybrid Model has been implemented on TALYS 1.95 code and it has selected as pre-equilibrium model. Constant Temperature Fermi Gas Model (CTFGM), Back Shifted Fermi Gas Model (BSFGM) and Generalised Super Fluid Model (GSM) have been used for level density model. Obtained results have been compared with the experimental data taken from literature. BSFGM and GSM results have been normalized to CTFGM to investigate level density model effects on reaction cross section calculations. Consequently it has been found that, level density models have an effect of 40% on the cross section calculations investigated in this study.

Abstract

Bu çalışmada 206Pb(p,2n)205Bi, 206Pb(p,3n)204Bi, 206Pb(p,5n)202Bi, 207Pb(p,2n)206Bi ve 207Pb(p,3n)205Bi reaksiyon tesir kesitleri TALYS 1.95 kodu ile hesaplanmıştır. Hesaplamalar için Geometri Bağımlı Hibrit Model TALYS 1.95 içerisine gömülmüş ve denge-öncesi model olarak kullanılmıştır. Sabit Sıcaklık Fermi Gaz Model (Constant Temperature Fermi Gas Model-CTFGM), Geri Kaydırmalı Fermi Gaz Model (Back Shifted Fermi Gas Model-BSFGM) ve Genelleştirilmiş Süper Akışkan Modelleri (Generalised Super Fluid Model-GSM) seviye yoğunluğu modelleri olarak seçilmiştir. Hesaplanan tesir kesitleri literatürden alınan deneysel verilerle karşılaştırılmıştır. Seviye yoğunluğu modellerinin reaksiyon tesir kesiti hesaplamaları üzerine etkisini araştırmak için, BSFGM ve GSM tesir kesiti hesaplamaları, CTFGM hesaplamalarına normalize edilmiştir. Sonuç olarak; seviye yoğunluğu modellerinin bu çalışmada incelenen tesir kesiti hesaplamaları üzerinde %40 oranında etkili olduğu bulunmuştur.
