dc.description.abstractDespite the quantum mechanical nature of the atomic nucleus, many important properties of nuclei and nuclear reactions can be well described by average statistical properties. Our knowledge of these properties does not only influence our basic understanding of the nucleus, but may also affect various applications ranging from cancer treatment within nuclear medicine, to astrophysics and the question of how our universe was formed. Given the potentially immense impact of new experimental observations of these statistical properties, it is imperative to improve our understanding of the uncertainties of the results: “with great power must also come – great responsibility”. To facilitate a more sophisticated statistical analysis of the data, the author has programmed a comprehensive revision of the software package used in the so-called Oslo method. Furthermore, current limits on the applicability of the method are explored. A new viewpoint for the analysis is established that allows for a simultaneous exploration of different experiments and may in addition overcome these constraints. Finally, a proof-of-concept was performed on how experiments at the Oslo Cyclotron Laboratory can also be used to extract information on nuclear fission properties.en_US
