SNAPS - Studies of Nuclear Properties for Explosive Astrophysical Processes

This poster will present the Studies of nuclear properties for explosive astrophysical processes (SNAPS) project that aims at constraining key reaction rates for p-isotope production and the rp-process. The main experimental approach of this project is to determine the nuclear level density and gamma strength function from particle-gamma coincidence data using the Oslo method. As an example of recent results, the work on constraining the cross section for the photodisintegration reaction 92Mo(p, gamma) will be presented. Nuclear reaction rates at astrophysical temperatures where calculated using the TALYS 1.6 code and combined with reaction network calculations for the scenario of the shock front of a supernova passing through the O-Ne layer of a 25 solar mass star and the impact of the constraint on final abundance calculations will be presented. The poster will also display the plans for the project.
