Description
I will present the results of our new study of (n,$\gamma$) reaction rate uncertainties of unstable isotopes near the magic neutron number $N=82$ on the i-process nucleosynthesis. Like in our previous work, in which we studied the impact of (n,$\gamma$) reaction rate uncertainties of unstable isotopes near $N=50$ on the i-process nucleosynthesis in the He-flash white dwarfs, we use Monte Carlo simulations with randomly varied multiplication factors for the reaction rates, constrained by nuclear physics uncertainties, to reveal the isotopes whose n-capture cross section uncertainties have the strongest impact on the predicted i-process nucleosynthesis yields, this time, at the second peak n-capture elements.
