IBM-1 Model ile çift-çift Fe İzotoplarının Nükleer Özelliklerinin İncelenmesi

Bu çalışmada, A60 bölgesinde bulunan bazı çift-çift Fe izotoplarının nükleer yapı özellikleri etkileşen bozonmodeli–1 (IBM-1) ile incelenmiştir. Bu incelemede, çift-çift Fe izotoplarının enerji seviyeleri ve elektromanyetikgeçiş oranları hesaplanmıştır. Hesaplamalar, temel banttaki ilk 41+ ve 21+ seviyelerinin oranlarını (R4+/2+ ), deneyselverileri 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 buHamiltonyenin parametreleri deneysel verilerden yola çıkılarak türetilmiştir. Daha sonra, bu izotopların enerjiseviyeleri ve B(E2) geçiş değerleri hesaplanmış ve deneysel veriler ile karşılaştırılmıştır. Ayrıca, yapısaldavranışları hakkında fikir sahibi olmak için 50,52,56,58,60,62,64,66,68,70Fe izotoplarının R4+/2+ = ?(41+)/?(21+), R0+/2+ =?(02+)/?(21+), R1(E2) = ?(?2: 41+ → 21+)/?(?2: 21+ → 01+) ve R2(E2) = ?(?2: 02+ → 21+)/?(?2: 21+ → 01+)oranlarının nötron sayılarına göre değişimi incelenmiştir.

Investigation of Nuclear Properties of even-even Fe Isotopes within the IBM-1 Model

In this study, the nuclear structure properties of some even-even Fe isotopes in the A60 region were investigated within the interacting boson model-1 (IBM-1). The energy levels and electromagnetic transmission rates of eveneven Fe isotopes were calculated in this investigation. The calculations include the ratios of the first 41 + and 21+energy levels (R4+/2+ ) , the other experimentally known energy levels, the B(E2) values and their ratios. First of all, a suitable model Hamiltonian was constructed and later the parameters of this Hamiltonian derived from the experimental data. Afterwards, the energy levels and B(E2) values of these isotopes were calculated and then compared with experimental data. Furthermore, changing of R4 +/2+ = ?(41+)/?(21+), R0+/2+ = ?(02+)/?(21+),R1(E2) = ?(?2: 41+ → 21+)/?(?2: 21+ → 01+) and R2 (E2) = ?(?2: 02+ → 21+)/?(?2: 21+ → 01+) ratios of 50,52,56,58,60,62,64,66,68,70Fe isotopes were investigated according to the neutron numbers to have an idea their structural behavior.
