Experimentally constrained $^{92}$Sr($n,\gamma$) reaction rate*

Although fission was discovered 80 years ago, fundamental data for neutron-induced production and destruction of fission products is missing. This data deficiency leads to reaction-rate uncertainties up to several orders of magnitude. An area particularly deficient in neutron-induced cross section data is the A=95 fission fragment region. To address this need, an experiment to indirectly determine the neutron-capture cross section on a short-lived fission fragment, $^{92}$Sr, was recently performed at the NSCL utilizing a total absorption spectrometer to measure the emitted $\gamma$ rays from $^{93}$Sr following the decay of $^{93}$Rb. The $\beta$-Oslo method is used in the ongoing data analysis to extract to extract level density and $\gamma$-decay strength, two key ingredients for calculating ($n,\gamma$) reaction rates. Preliminary analysis of measured $\gamma$-ray spectra will be presented here. The results will also provide crucial tests for model input to infer the ($n,\gamma$)$^{95}$Sr reaction rate, which is a high-yield fission product.
