Research at the department

In Uppsala you will find Sweden’s perhaps largest research effort in physics and astronomy. The research includes string theory, particle physics and nuclear physics, atomic physics and material science, as well as studies of the origin of the planetary system and the universe itself.

Basic research aimed at revealing the fundamental laws of Nature and finding our place in the universe, is found side by side with applied research on new materials and energy technology. Uppsala is an active participant in a large number of leading international research collaborations such as CERN, ESO, ESA, AMANDA and MAXLab. Over the years Uppsala has been awarded two Nobelprizes through Manne Siegbahn and his son Kai Siegbahn.

Applied Nuclear Physics

In Applied Nuclear Physics experimental research is performed in the fields of present and future nuclear energy production with an emphasis on diagnostics and nuclear data.

Astronomy and Space Physics

The astronomical research in Uppsala ranges from planetary systems, stellar physics, to the large scale structure of the Universe. Theoretical and observational research is complemented with development of instruments.


FREIA is a large scale facility for research and development of new
accelerators and instrumentation for accelerator based research.

High Energy Physics

Materials Physics

The exploration of dimensionality aspects of phase transitions as well as all advanced production of devices requires good knowledge of materials. That knowledge is our mission.

Materials Theory

The activities at the Division of Materials Theory cover a wide range of topics within materials and condensed matter physics, including magnetism, superconductivity, the physics of the Earth's deep interior, nanoscale physics, hydrogen storage and biological physics.

Molecular and Condensed Matter Physics

We have a broad research scope based on experimental studies of the electronic structure of matter. Motivated by issues such as energy, environment as well as fundamental topics, we investigate systems ranging from free atomic, molecular and cluster species to liquids, molecular materials and single crystal hard materials with synchrotron-radiation-based spectroscopies as our main tools.

Nuclear Physics

Physics Education Research

The activities of the group are centred principally around the interplays between learning and the form and content of physics and related engineering curricula and teaching.

Theoretical physics

The research in theoretical physics spans a large spectrum of physical problems, from the origin of the universe, where both the forces and matter are represented by oscillating strings, via proteins that fold and form knots, to the structure of the particles colliding in our accelerators.

Presentation on the Neutron Resonance Analysis School 2011

Type : 
Applied Nuclear Physics

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.
