Abstract

Bu çalışmada, A50 bölgesindeki bulunan bazı çift-çift Fe izotoplarının nükleer yapı özellikleri etkileşen bozon modeli–1 (IBM-1) ile incelenmiştir. Bu incelemede, çift-çift 50,52,56,58Fe izotoplarının enerji seviyeleri ve elektromanyetik geçiş oranları hesaplanmıştır. Hesaplamalar, temel banttaki ilk 4_1^+ ve 2_1^+ seviyelerinin oranlarını ("R" _("4" ^"+" "/" "2" ^"+" )), deneysel verileri bilinen diğer enerji seviyelerini, B(E2) geçiş değerlerini ve bunların oranlarını içermektedir. Öncelikle, incelenen izotopların deneysel enerji oranlarına bakılarak uygun model Hamiltonyeni oluşturulmuş ve sonra bu Hamiltonyenin parametreleri deneysel verilerden yola çıkılarak türetilmiştir. Daha sonra, bu izotopların enerji seviyeleri ve B(E2) geçiş değerleri hesaplanmış ve deneysel veriler ile karşılaştırılmıştır. Ayrıca, yapısal davranışları hakkında fikir sahibi olmak için 50,52,56,58Fe izotoplarının "R" _("4" ^"+" "/" "2" ^"+" )=E(4_1^+ )/E(2_1^+ ), "R" _("0" ^"+" "/" "2" ^"+" )=E(0_2^+ )/E(2_1^+ ), "R" _"1" (E2)=B(E2:4_1^+→2_1^+)/B(E2:2_1^+→0_1^+) ve "R" _"2" (E2)=B(E2:0_2^+→2_1^+)/B(E2:2_1^+→0_1^+) oranlarının nötron sayılarına göre değişimi incelenmiştir
