Abstract

Recent astronomical observations indicate that additional nucleosynthesis pathways are required to understand some atypical elemental abundance patterns revealed by new observations. One such process that can help to explain these observations is the intermediate neutron-capture process (i process). The nuclear properties of isotopes involved in this nucleosynthesis pathway are experimentally well constrained with the exception of the neutron-capture reaction rates, which are provided almost entirely by theory. In this paper, the first experimentally constrained reaction rate on the Kr87(n,γ)Kr88 reaction is provided by employing the β-Oslo method. The impact of this reaction on the abundance of rubidium within the i process is investigated.
