AB  - Innuclear medicine, radiopharmaceuticals are used for diagnosis or treatmentpurposes. Radiopharmaceuticals containing radionuclide in their structure areproduced by reactors, generators or cyclotrons and are generally used for scintigraphyor tomographic investigations. The produced radionuclides can be given to thehuman body together with organic or inorganic substances. In this study,the production reaction cross sections were calculated for two selectedradiopharmaceutical nuclei (99Tc and 115In) using the semi-empirical cross section formula for the (n, α) reactions developed by Tel et al. (2008).The density depending on (n, α) reaction cross sections were also investigated withthe four Skyrme Hartree Fock parameters (S3, T3, SKM and SKM*). While the calculatedvalue from the semi-empirical formuladeveloped by Tel et al. (2008) gave reasonable results, the density-dependentcalculations were observed lower values than that of experimental values.

N2  - Nükleer tıpta, radyofarmasötiklertanı veya tedavi amacıyla kullanılmaktadır. Yapılarında radyonüklid içerenradyofarmasötikler, reaktör, jeneratör veya siklotronlarla üretilirler ve genelliklesintigrafik veya tomografik incelemelerde kullanılır. Üretilen radyonüklidler,organik veya inorganik maddelerle birlikte vücuda verilebilir. Bu çalışmada, (n,α) reaksiyonları için Tel ve arkadaşları (2008) tarafından geliştirilenyarı-ampirik tesir kesit formülü kullanılarak seçilen iki radyofarmasötikçekirdek (99Tc ve 115In) için üretim reaksiyonu tesirkesitleri hesaplanmıştır. Ayrıca, yoğunluğa bağlı ampirik (n, α) (2008) nükleerreaksiyon tesir kesitleri dört Skyrme Hartree Fock parametreleri (S3, T3, SKMve SKM*) kullanılarak da incelenmiştir. Telve ark. (2008) tarafından geliştirilen yarı ampirik formülünden hesaplanandeğer uyumlu çıkarken, yoğunluğa bağlı hesaplamaların deneysel değerlerden dahaaşağıda olduğu gözlemlenmiştir.
