Nükleer astrofizikte ve nükleer enerji uygulamalarında
önemli bir yere sahip olan nötron yakalama reaksiyonlarının tesir kesiti
analizini yapmak amacıyla, bu çalışmada ¹²²Te(n,g)¹²³Te,  ¹²³Te(n,g)¹²⁴Te,  ¹²⁴Te(n,g)¹²⁵Te,  ¹²⁵Te(n,g)¹²⁶Te,  ¹²⁶Te(n,g)¹²⁷Te,  ¹²⁸Te(n,g)¹³⁰Te ve  ¹³⁰Te(n,g)¹³¹Te
reaksiyonlarının nötron yakalama tesir kesitleri TALYS 1.6 bilgisayar kodu
kullanılarak hesaplanmıştır. Hesaplamalarda beş farklı şiddet fonksiyonu ve
altı farklı nükleer seviye yoğunluğu modeli kombinasyonu kullanılmıştır. Elde
edilen bu kombinasyonlar birbirleriyle ve bu reaksiyonların deneysel verileri
ile karşılaştırılmıştır.
