Nuclear structures of the atomic nuclei can be theoretically investigated by using nuclear shell model. Generally, a doubly closed-shell nucleus has been considered as inert core and the nucleons outside the core are taken into account in the calculation. It is assumed that the nucleons in the inert core do not move but each valance nucleon out of the core moves under an average potential created by the others. The self-conjugate (N=Z) moderate mass nuclei region is one of the region for the investigation of several phenomena because of the maximum spatial overlap of neutrons and protons. In this study, the nuclear structures of the moderate mass N=Z have been analyzed in the scope of the nuclear shell model by using KSHELL computer code. In the calculations, doubly magic 56Ni were taken as core and p3/2, f5/2 and p1/2 single particle orbits were used as valance orbits. Different two-body interactions have been taken into account. The results have been compared with each other and the available values existing in the literature.

Atom çekirdeklerinin nükleer yapıları, nükleer kabuk modeli kullanılarak teorik olarak incelenebilir. Genel olarak, bir çift kapalı kabuk çekirdeği kor çekirdek olarak ele alınır ve kor dışındaki nükleonlar hesaplamada dikkate alınır. Kor çekirdekteki nükleonların hareket etmediği, ancak kor dışındaki valans nükleonlarının, diğerleri tarafından yaratılan ortalama bir potansiyel altında hareket ettiği varsayılmaktadır. Öz-eşlenik (N=Z) orta ağırlığa sahip kütleli çekirdeklerin bölgesi, nötronların ve protonların azami uzaysal çakışması nedeniyle, bazı nükleer olguların araştırılması için uygun bölgelerden birisidir. Bu çalışmada, orta ağırlıktaki N=Z çekirdeklerinin nükleer yapı özellikleri, nükleer kabuk modeli kapsamında KSHELL bilgisayar kodu kullanılarak araştırılmıştır. Hesaplamalarda kor çekirdek olarak çift sihirli 56Ni ele alınmış ve valans orbitalleri olarak p3/2, f5/2 ve p1/2 tek parçacık seviyeleri kullanılmıştır. Farklı iki cisim etkileşmeleri ele alınmıştır. Sonuçlar birbirleriyle ve literatürdeki mevcut değerlerle karşılaştırılmıştır.
