Abstract

In cases where experimental studies cannot be carried out and there is no experimental data with it, studies carried out with theoretical models shed light on the researchers' knowledge of different data. The most important of this data is the measurable or calculatable influence cross-section value, which is defined as the probability of a reaction occurrence. Examining the possible effects of different models in the calculation of the effect section is important for the correct calculation of this value. The most important data, the cross section of influence, has taken its place in the radioisotope world as well as in many areas of nuclear physics. With developing technology and advancing science, radioisotopes have widespread and diversified uses. Most commonly, radioisotopes are used in medical diagnosis and treatment applications. Among the many radioisotopes used for this purpose, 191-199Au radioisotopes are also important in terms of both their benefits and characteristics in medical applications. In this respect, the study aimed to investigate the effects of different nuclear level density models in production impact cross-section calculations of 191-199Au radioisotopes with deuteron reference. Theoretical cross sections using the TALYS code have been simulated for all isotopes. The results of the calculations obtained were compared with each other and with the experimental data in the literature and it was aimed to determine the most compatible level density models according to the reaction situations examined.

Platinyum Element İçin 191-199Au Medikal İzotop Üretim Tesir Kesitlerinin ve Seviye Yoğunluk Modellerinin Etkisinin İncelenmesi

Abstract

Deneysel çalışmaların yapılamadığı ve bununla birlikte deneysel verilerin bulunmadığı durumlarda, teorik modellerle yapılan çalışmalar, araştırmacıların farklı veriler hakkındaki bilgilerine ışık tutmaktadır. Bu verilerden en önemlisi, bir reaksiyonun oluşma olasılığı olarak tanımlanan ölçülebilir veya hesaplanabilir tesir kesiti değeridir. Tesir kesiti bölümünün hesaplanmasında farklı modellerin olası etkilerinin incelenmesi, bu değerin doğru hesaplanması açısından önemlidir. En önemli veri olan tesir kesiti, radyoizotop dünyasında olduğu gibi nükleer fiziğin birçok alanında da yerini almıştır. Gelişen teknoloji ve ilerleyen bilim ile radyoizotopların yaygın ve çeşitli kullanımları vardır. En yaygın olarak radyoizotoplar medikal tanı ve tedavi uygulamalarında kullanılmaktadır. Bu amaçla kullanılan birçok radyoizotop arasında 191-199Au radyoizotopları da tıbbi uygulamalarda hem yararları hem de özellikleri açısından önemlidir. Bu bağlamda çalışmada, 191-199Au radyoizotoplarının üretim tesir kesit hesaplamalarında farklı nükleer seviye yoğunluk modellerinin etkilerinin döteron referansı ile araştırılması amaçlanmıştır. TALYS kodunun kullanıldığı teorik kesitler tüm izotoplar için simüle edilmiştir. Elde edilen hesaplamaların sonuçları birbirleri ve literatürdeki deneysel verilerle karşılaştırılmış ve incelenen reaksiyon durumlarına göre en uyumlu seviye yoğunluk modellerinin belirlenmesi amaçlanmıştır.
