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.
