Session 15: Nuclear Astrophysics and Structure
- Luna Pellegri (University of the Witwatersrand and iThemba LABS)
The study of photo-nuclear reactions is crucial for understanding nuclear structure and astrophysical processes. The PANDORA (Photo-Absorption of Nuclei and Decay Observation for Reactions in Astrophysics) project aims to systematically investigate these reactions in nuclei with mass numbers below 60. We will use virtual photon exchange through proton scattering and high-intensity real-photon...
The PANDORA (Photo-Absorption of Nuclei and Decay Observation for Reactions in Astrophysics) project is dedicated to both experimental and theoretical analysis of photo-nuclear reactions involving light nuclei with a mass below $A = 60$. This research is particularly significant in the context of ultra-high-energy cosmic ray (UHECR) investigations, where the primary mode of energy attenuation...
The Brink-Axel hypothesis assumes that photo-de-excitation only depends on the emitted γ-ray energy Eγ and not the detailed structure of the initial and final states (spin and parity) involved in the transition as it is the case for photo-excitation process. While the hypothesis is widely used for all PSF energy regions such as the giant dipole resonance (GDR), it remains under investigation...
The nuclear physics group at the University of Oslo (UiO) and the Oslo Cyclotron Laboratory (OCL) have developed a method, known as the Oslo method, to extract the nuclear level den- sity(NLD) and Gamma-ray strength function (GSF). These quantities are important because they are inputs that are used in the Hauser-Fesbach statistical model calculations. These calculations are used to predict...
