Ydinspektroskopiaryhmä

The Nuclear Spectroscopy group utilises in-beam gamma-ray and electron as well as decay-spectroscopic methods to shed more light on the microscopic structure of the nucleus through the studies of exotic nuclei, mainly along the proton drip line and in the region of heavy elements. These methodologies in conjunction with heavy-ion beams form the backbone for experimental studies of the Nuclear Spectroscopy Group.

Tutkimusryhmän kuvaus

In atomic nuclei, the interplay of three fundamental forces (electromagnetic, strong and weak) between strongly interacting individual fermions generates an effective nucleon-nucleon interaction. As a result, nuclei present us with one of Nature's most intricate examples of the interplay between single-particle motion, collectivity and pairing in a quantum many-body system. A theoretical microscopic description of the nucleus is extremely difficult due to relatively large number of nucleons, which, in turn, is too small for a reliable statistical approach. The Nuclear Spectroscopy group utilises in-beam gamma-ray and electron as well as decay-spectroscopic methods to shed more light on the microscopic structure of the nucleus through the studies of exotic nuclei, mainly along the proton drip line and in the region of heavy elements. These methodologies in conjunction with heavy-ion beams form the backbone for experimental studies of the Nuclear Spectroscopy Group.
