Abstract

Bu çalışmada, Paladyum izotoplarının (102,104,106,108,110Pd) (n,2n), (n,p) ve (n,) reaksiyon tesir kesitleri Empire-3.2.3 (Malta) istatistiksel model kodu kullanılarak reaksiyon eşik değerinden 20 MeV’e kadar nötron enerjilerinde hesaplanmıştır. Hesaplamalar, dört farklı nükleer seviye yoğunluğu modeli (Genelleştirilmiş Süper Akışkan modeli, Gelişmiş Genelleştirilmiş Süper Akışkan modeli, Gilbert-Cameron modeli ve Hartree-Fock-Bogoliubov mikroskobik modeli) kullanılarak yapılmıştır. Hesaplardan elde edilen sonuçlar, EXFOR kütüphanesinde bulunan deneysel verilerle ve ENDF kütüphanesinden alınan ENDF/B-VIII.0 (USA,2018), TENDL-2019 (TALYS, 2019) ve JENDL-5 (Japan,2021) değerlendirilmiş verilerle karşılaştırılmıştır. 14.5 MeV civarında deneysel ve değerlendirilmiş verilerle karşılaştırıldığında, sonuçlar genel olarak tutarlı bir uyum göstermektedir.

The (n,2n), (n,p) and (n,a) cross section calculations of the palladium isotopes using different level density models from the reaction threshold to 20 MeV

Abstract

In this study, reaction cross sections of Palladium isotopes (102,104,106,108,110Pd) (n,2n), (n,p) and (n,) were calculated for neutron energies from reaction threshold to 20 MeV by using Empire-3.2.3 (Malta) statistical model code. The calculations are performed by using four different nuclear level density models (Generalized Superfluid Model, Enhanced Generalized Superfluid Model, Gilbert-Cameron Model, and Hartree-Fock-Bogoliubov Microscopic Model). The obtained results from calculations are compared with the existing experimental data taken from EXFOR library and the evaluated nuclear data library of ENDF/B-VIII.0 (USA, 2018), TENDL-2019 (TALYS, 2019) and JENDL-5 (Japan, 2021) data taken from ENDF. Comparing with experimental and evaluated data around 14.5 MeV, results show generally consistent agreement.
