The use of radioisotopes has become increasingly widespread and diversified thanks to advancing technology and scientific advances. The most widely used field of radioisotopes are medical diagnosis and treatment applications. Among the many radioisotopes used for these purposes, there are also 75-77Br radioisotopes due to their characteristics and benefits in applications. As a result of the impact and value of radioisotopes in medical applications, studies on the production routes of these isotopes have also contributed to the literature. In this context, the use of different theoretical models is quite common in obtaining various parameters that can inform researchers in cases where experimental studies cannot be carried out. The cross–section value, which can be explained briefly as the probability of a reaction, is an important parameter for the researchers and one of the effective factors in the calculation of this value is the level density models. Considering all these, in this study, it is aimed to investigate the effects of some level density models in the production cross–section calculations with some (p,xn) reactions of 75-77Br radioisotopes. In calculations, 1.9 version of TALYS code was used and the results obtained were compared with the experimental data available in the literature.

75-77Br Radyoizotoplarının Üretim Tesir Kesiti Hesaplamalarında Bazı Seviye Yoğunluğu Modellerinin Etkilerinin İncelenmesi

Öz

Radyoizotopların kullanım alanları, gelişen teknoloji ve bilimsel ilerlemeler sayesinde giderek yaygınlaşmış ve çeşitlenmiştir. Radyoizotopların en yaygın kullanıldığı alan ise medikal teşhis ve tedavi uygulamalarıdır. Bu amaçlarla kullanılan pek çok radyoizotop arasında karakteristik özellikleri ve uygulamalardaki faydaları nedeniyle 75-77Br radyoizotopları da bulunmaktadır. Medikal uygulamalarda radyoizotopların sahip oldukları etki ve değer neticesinde bu izotopların üretim rotaları ile ilgili çalışmalar da literatüre katkı sağlayan çalışmalar olmuştur. Bu kapsamda, deneysel çalışmaların gerçekleştirilemediği durumlarda araştırmacılara bilgi verebilecek çeşitli parametrelerin elde edilmesinde farklı teorik modellerin kullanımı oldukça yaygındır. Kısaca bir reaksiyonun gerçekleşme ihtimali olarak açıklanabilecek tesir kesiti değeri de araştırmacılar için önemli bir parametredir ve bu değerin hesaplanmasında etkili faktörlerden biri de seviye yoğunluğu modelleridir. Tüm bunlar göz önüne alınarak bu çalışmada, 75-77Br radyoizotoplarının bazı (p,xn) reaksiyonları ile üretim tesir kesiti hesaplamalarında bazı seviye yoğunluğu modellerinin etkilerinin araştırılması amaçlanmıştır. Hesaplamalarda TALYS kodunun 1.9 sürümü kullanılmış ve elde edilen hesaplama sonuçları literatürde mevcut olan deneysel veriler ile karşılaştırılmıştır.
