Description
The 25Mg nucleus plays a critical role in nucleosynthesis processes, particularly in slow neutron capture process (s-process). The (α,n) reaction on 22Ne producing 25Mg is the main neutron source in massive stars. In addition, 25Mg is the origin of the formation of two other nuclei in stellar environments, the proton capture on 25Mg, forms 26Al and the neutron capture on 25Mg, forms 26Mg. The Jπ assignments of 25Mg has a significant importance in determining the previous astrophysical reactions rates.
Theoretical results employing our PSDPF effective interaction, including excitation energies, spin-parity assignments, and transition probabilities, are systematically compared with experimental data. Our interaction describes quite well these observables that are crucial in calculating the above astrophysical reaction rates. We will present in our contribution a detailed discussion of our work.
