Contributed Talk

Accurate predictions of $\alpha$-induced reactions on medium mass nuclei are critically reliant on the alpha optical model potential ($\alpha$OMP). At the energies relevant to explosive nucleosynthesis, the behavior of the $\alpha$OMP is poorly constrained by existing data, leading to orders of magnitude variation in thermonuclear reaction rates undermining the predictive accuracy of stellar...

Contributed Talk

The r-process nucleosynthesis produces roughly half of the heavy elements found in nature. Among its nuclear physics inputs, the $\beta$-decay half-lives of extremely neutron-rich nuclei is a key ingredient. Since experimental data in this region is limited, we need theoretical predictions that are globally applicable. Here we present improvements to the existing self-consistent RHB+RQRPA...
