One of the common methods used to investigate the nuclear structures of atomic nuclei is the nuclear shell model. Like the arrangement of atomic electrons in orbitals, in the nuclear shell model, protons and neutrons are thought to be placed in orbits within the nucleus in accordance with the Pauli exclusion principle. These orbitals group together to form shells, which if all possible levels in a shell are filled, the shell is said to be closed. Atomic nuclei with closed shells are very stable and in nuclear shell model calculations, the valence nucleons more than these nuclei are included in the calculations. In this study, the nuclear shell model was used to investigate the nuclear structures of He and Be isotopes. 4He nucleus have been taken as a closed-shell core nucleus. Considering p3/2 and p1/2 as single-particle orbits in model space, different two-body interactions are used between valence nucleons. The results from the interactions giving better results were compared with each other and with the available experimental values.
