In this study, fission cross section of 230,232Th ve 236,238,239,240,241,242,244Pu nuclei have been carried out in the 1-20 MeV incident energy neutrons. ALICE-ASH and CEM95 computer programs was used for calculations. In CEM95 calculations, all sistematics of level density parameters (IFAM) was used. In ALICE-ASH calculations, RFRM (Rotation-Finite-Range Model) and RLDM (Rotation-liquidDrop Model) was used. The calculated fission cross section was compared with the experimental data taken from the Experimental Nuclear Reaction Data (EXFOR).

Bu çalışmada, 230,232Th ve 236,238,239,240,241,242,244Pu çekirdeklerinin fisyon tesir kesitleri 1-20 MeV gelme enerjili nötronlar için hesaplandı. Hesaplamalar, tesir kesiti hesaplamalarını farklı modellerle ele alan ALICE-ASH ve CEM95 bilgisayar programları ile yapıldı. CEM95 ile yapılan hesaplamalarda seviye yoğunluğu parametresinin (IFAM) tüm sistematikleri kullanıldı. ALICE-ASH ile yapılan hesaplamalarda RFRM (Rotation-Finite-Range Model) ve RLDM (Rotation-liquid-Drop Model) modelleri kullanıldı. Hesaplanan fisyon tesir kesitleri Deneysel Nükleer Reaksiyon Veri (Experimental Nuclear Reaction Data-EXFOR) kütüphanesinden elde edilen deneysel değerlerle karşılaştırıldı.
