Atomic nuclei are formed by a sufficiently small number (< 300) of nucleons, i.e., protons and neutrons, such that a single nucleon can make a substantial contribution to the behaviour of the entire nucleus and to the properties of its excited states. This aspect is further enhanced by the fermionic quantum character of the nuclear system which leads to the formation of nuclear shell structure.
We investigate the role of single-particle effects on the properties of the nuclear quantum system in stable and in radioactive nuclei by using electron-scattering techniques at our in-house electron accelerator S-DALINAC or by using the method of gamma-ray spectroscopy at ion-accelerator facilities world-wide.
Our results contribute to an improved quantitative understanding of the nuclear quantum system.
We further contribute to the developments of improved experimental techniques for quantitative research on nuclear single-particle properties.
