Constraining i-process Nucleosynthesis via the Neutron-Capture Cross sections of 102,103Mo
ORAL
Abstract
Recent observations and stellar evolution models suggest that an intermediate process, known as the i-process, exists between the s- and r-processes, and is necessary to explain observed abundances in the Ge-Te region. Uncertainties associated with nuclear physics inputs, especially neutron-capture cross sections limit the predictive power of i-process simulations. In this work the $\beta$-Oslo method was used to study $^{103,104}$Mo at the NSCL via the $\beta$-decay of $^{103,104}$Nb which were detected using the Summing NaI(Tl) (SuN) total absorption spectrometer. Results on the NLD, $\gamma$SF, neutron-capture cross sections of $^{102}$Mo and $^{103}$Mo, and i-process calculations from the Nucleosynthesis Grid (NuGrid) Collaboration will be presented.
