Description
Nuclides in the vicinity of double magicity have simple structure, which can be described with the shell model. The nuclei is treated like closed, well bounded core, built with magic number of nucleons, and walence nucleons. The excitation-energy spectrum is dominated by single particle extitations. Therefore, there is a great need of systematic investigation of the nuclear structure of the nuclei in this area, it is crucial to understand how the nuclear structure evolve with addition of susbsequent nuleons. Obtaining Ni-63 decay scheme is part of those systematic investigations.
The experiment was performed in Institut Laue–Langevin (ILL) in Grenoble . Excited states of Ni-63 were populated in (n,γ) reaction. During the data analysis there were 9 new or confirmed γ ray transitions found. One excited level proposed within previous investigation of the Ni-63 was unsobserved in the analysed dataset. The branching factors were calculated for all γ ray transitions. Additionaly, shell model calculations with using different effective interactions were performed and compared to the experimental results.
This work was done in EXILL collaboration.
