School and society

The department of physics and astronomy offers information to and cooperation with the society in various ways, such as organizing exhibitions and demonstrations to schools and the general public, taking part in various working groups within our respective fields of research and by performing commissioned research and education (see links to the left).

Presentation on the Neutron Resonance Analysis School 2011

The presentation is given as part of the Neutron Resonance Analysis School I attended in 2011. I will present the general evaluation process; describe the resonance parameters and how they are represented in the ENDF format. Also, a brief description of the general theoretical models used in the analysis of neutron resonance data - R-matrix theory (the single-level Breit-Wigner, the multi-level Breit Wigner and Reich Moore approximation) for the resolve region and the Hauser-Feshbach theory for the unresolved resonance region will be covered. Finally, the Doppler broadening of the single level Breit-Wigner formalism for resonance absorption will be presented.
