57Co RADYOİZOTOPU ÜRETİMİ İÇİN BAZI ALFA GİRİŞLİ REAKSİYONLARIN UYARILMA FONKSİYONLARININ İNCELENMESİ

Sağlık alanında tedavi veya teşhis amacıyla kullanılan radyoizotoplar genellikle siklotron veya reaktörler ile üretilmektedir. Radyoizotopların hangi reaksiyon ile üretileceğini, üretimde kullanılacak olan mermi parçacıklarının enerjisini, hedef çekirdek ve reaksiyonun tesir kesitleri belirlemektedir. 57Co radyoizotopu genellikle B12 vitamini eksikliği için Schilling testinde kullanılmaktadır. Gastrointestinal B12 vitamini emilim tayini, nükleer tıp laboratuvarları tarafından sunulan ilk testler arasında yer almaktadır. Bu çalışmada, alfa parçacıkları ile gerçekleştirilen 55Mn(⍺,2n), 54Fe(⍺,p), 56Fe(⍺,2n+p), 59Co(⍺,2n+⍺), 59Co(⍺,x) ve 58Ni(⍺,p+⍺) reaksiyonları ile 57Co radyoizotopunun üretim reaksiyonlarının uyarılma fonksiyonları incelenmiştir. TALYS 1.8 programı kullanılarak yapılan hesaplamalar, EXFOR kütüphanesinden alınan deneysel veriler ve teorik hesaplama sonuçları karşılaştırılarak reaksiyon tesir kesitleri grafikleri sunulmuştur.
