AB  - Bu çalışmada, Samaryum ve Gadolinyum elementlerinin farklı izotopları için (n,2n) reaksiyonlarının tesir kesiti hesaplamalarında denge ve denge-öncesi nükleer reaksiyon modellerinin etkilerinin incelenmesi amaçlanmıştır. Bu kapsamda, Samaryum elementinin 144, 148, 150, 152 ve 154 kütle numaralı izotopları ile Gadolinyum elementinin 155, 156, 157, 158 ve 160 kütle numaralı izotopları için (n,2n) reaksiyonlarına ait tesir kesiti hesaplamalarında TALYS ve EMPIRE isimli kodlar kullanılmıştır. TALYS kodunun 1.8 versiyonun kullanıldığı hesaplamalarda İki Bileşenli Eksiton Model ve Hauser-Feshbach Model, EMPIRE kodunun 3.2 versiyonun kullanıldığı hesaplamalarda ise PCROSS Eksiton Model ve Hauser-Feshbach Model denge ve denge-öncesi etkilerin analiz edilebilmesi için seçilmiş olan modellerdir. Elde edilen hesaplama sonuçları, EXFOR veritabanından temin edilen deneysel verilerle karşılaştırılmış ve bulgular her bir reaksiyon için grafiksel olarak görselleştirilmiştir. Çalışmanın sonuçları bir bütün olarak değerlendirildiğinde çıktıların literatürde de mevcut olan iki durumu destekleyecek nitelikte olduğu söylenebilmektedir. Bunlardan ilki deneysel çalışmaların gerçekleştirilemediği durumlarda teorik hesaplama yöntemlerinin bilimsel araştırmalar için bir alternatif olabileceği iken diğeri ise bu tarz çalışmaların hesaplamalarda kullanılan teorik modellerin gelişimine destek sağlayabileceği öngörüsüdür.

N2  - This study aims to investigate the effects of equilibrium and pre-equilibrium nuclear reaction models on cross-section calculations for (n,2n) reactions of different isotopes of Samarium and Gadolinium elements. In this context, cross-section calculations for (n,2n) reactions of the isotopes 144, 148, 150, 152, 154 of Samarium and 155, 156, 157, 158, 160 of Gadolinium elements were performed using the TALYS and EMPIRE codes. In the calculations performed with version 1.8 of the TALYS code, the Two-Component Exciton Model and Hauser-Feshbach Model were employed, while in the calculations using version 3.2 of the EMPIRE code, the PCROSS Exciton Model and Hauser-Feshbach Model were chosen to analyze the effects of equilibrium and pre-equilibrium mechanisms. The obtained theoretical results were examined with experimental data sourced from the EXFOR database, and the findings were visualized graphically for each reaction. When the outcomes of the study are examined as a whole, it is possible to say that the outputs support two situations that are also present in the literature. The first among them is that theoretical calculation methods can be an alternative for scientific research in situations where experimental works may not possible to be carried out, while the other is the prediction that such studies can support the development of theoretical models used in calculations.
