Changes in the course due to coronavirus

Autumn 2020 the exams of most courses at the MN Faculty will be conducted as digital home exams or oral exams, using the normal grading scale. The semester page for your course will be updated with any changes in the form of examination.

See general guidelines for examination at the MN Faculty autumn 2020.

Course content

This course will provide the students with an understanding of the main astrophysical processes to produce elements in the cosmos. In particular, the connection of nuclear physics data to astrophysical relevant cross-sections will be covered, which includes hands-on experience with the state-of-the-art TALYS reaction code, to deepen the understanding of the interplay of nuclear physics and astrophysics.

Learning outcome

After completing this course:

  • you will have knowledge of how elements heavier than iron could be formed in astrophysical environments, especially the s-process, the r-process, and the p-process.
  • you will have a detailed knowledge of the importance of nuclear structure physics and nuclear reactions underlying nuclear astrophysical processes.
  • you will have a detailed knowledge of the nuclear reactions models, such as the Hauser-Feshbach formalism, relevant to nuclear astrophysics.
  • you will be able to calculate nuclear cross-sections e.g. neutron capture cross-sections.
  • you will have hands-on training in running the state-of-of-the-art reaction code TALYS using both experimental and theoretical level densities and gamma strength functions as inputs.
  • you will have knowledge of experimental nuclear physics methods and techniques used for measuring nuclear properties for nuclear astrophysical processes.

Admission to the course

Send a short application to studieinfo@fys.uio.no. Only students enrolled in the programme Physics (master's two years), programme option Nuclear and Particle Physics (programme option), or students enrolled in the programme Astronomy (master's two years), may apply. This course should be a part of your approved Study Plan. Contact the Department of Physics if you are unsure if you are eligible to apply.

Overlapping courses


The course will be given as an intensive course over two weeks with 30 hours of lectures and 30 hours of problem sessions and hands-on calculations using the TALYS code. There will be a mandatory report, with a deadline several weeks after the intensive course.

As the teaching involves laboratory and/or field work, you should consider taking out a separate travel and personal risk insurance. Read about your insurance cover as a student.

Cost of taking the course

The location of the intensive course may be in Oslo or abroad. If given abroad there will be travel and housing costs. Students can apply to have these costs covered, and the selection of students for grants is based on the relevance of the course for their PhD or master thesis.  


The examination consists of the report on TALYS calculations. 

It will also be counted as one of the three attempts to sit the exam for this course, if you sit the exam for one of the following courses: FYS9525 – Advanced Nuclear Reactions and Applications in Astrophysics

Language of examination

The examination text is given in English, and you submit your response in English.

Grading scale

Grades are awarded on a pass/fail scale. Read more about the grading system.

Facts about this course


The course will not be offered autumn 2020.

If the course is offered, a minimum of four students is required for ordinary lectures to take place. If less than four students participate, an exam will be given, but one should not expect ordinary teaching.
