Abstract

The neutron capture reaction is one of the important reactions that provides the determination of the structural properties of the nucleus and detailed information about the capture reaction mechanisms. In this study, cross section values of 89Y(n,g)90Y reaction, which is a neutron capture reaction, were calculated with TALYS computer code up to 10 MeV incident particle energy using different level density models. In the calculations, back-shifted Fermi gas model (BSFGM), constant temperature model (CTM), generalized superfluid model (GSM), and collective semi-classical Fermi gas model (CSCFGM) were preferred. The obtained results were compared with the data taken from the experimental database. In addition, the quality factors of the models were presented in the table. As a result of the calculations, it has been presented that the CSCFGM, which takes the collective effects into account basically, is more successful model to reproduce the experimental data and that the collective effects play a dominant role on the neutron capture reaction cross sections. Therefore, it has been demonstrated that CSCFGM is a model, which can be used for neutron capture reaction analyses in the future.

Özet

Nötron yakalama reaksiyonu, çekirdeğin yapısal özelliklerinin belirlenmesini ve yakalama reaksiyon mekanizmaları hakkında detaylı bilgi sahibi olunmasını sağlayan önemli reaksiyonlardan bir tanesidir. Bu çalışmada, nötron yakalama reaksiyonu olan 89Y(n,g)90Y reaksiyonuna ait tesir kesiti değerleri farklı seviye yoğunluğu modelleri kullanılarak 10 MeV gelen parçacık enerjisine kadar TALYS bilgisayar kodu ile hesaplanmıştır. Hesaplamalarda, geri kaydırılmış Fermi gaz modeli (Back-Shifted Fermi Gas Model-BSFGM), sabit sıcaklık modeli (Constant Temperature Model-CTM), genelleştirilmiş süperakışkan model (Generalized Superfluid Model-GSM) ve kollektif yarı-klasik Fermi gaz modeli (Collective Semi Classical Fermi Gas Model-CSCFGM) tercih edilmiştir. Elde edilen sonuçlar deneysel veri tabanından alınan veriler ile karşılaştırılmıştır. Ayrıca, modellere ait kalite faktörleri tablo halinde sunulmuştur. Yapılan hesaplamalar sonucunda kollektif etkileri en temelde hesaba dahil eden CSCFGM modelin deneysel verileri tekrar sağlamada daha başarılı olduğu ve kollektif etkilerin nötron yakalama reaksiyon tesir kesitleri üzerinde baskın rol oynadığı sunulmuştur. Dolayısıyla, ileride yapılacak olan nötron yakalama reaksiyon analizlerinde CSCFGM’nin kullanılabilecek bir model olduğu ortaya konmuştur.
