Advanced Nuclear Reactions and Applications to Astrophysics

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.This course is designed to give students with a background in nuclear physics an introduction on how nuclear physics data is used in astrophysics. During the course the students are introduced to the reaction code TALYS which is a popular tool for numerically analyzing nuclear reactions.

Topics covered:

• How elements heavier than iron could be formed in astrophysical environments, especially the s-process, the r-process and the p-process.
• Importance of nuclear structure physics and nuclear reactions underlying nuclear astrophysical processes.
• Nuclear reactions models, such as the Hauser-Feshbach formalism, relevant to nuclear astrophysics.
• Calculations of nuclear cross-sections e.g. neutron capture cross-sections.
• 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.
• Experimental nuclear physics methods and techniques used for measuring nuclear properties for nuclear astrophysical processes.
