Branching Ratio Measurements of the Harvested Isotope <sup>111</sup>Ag

ORAL

Abstract

Our understanding on the distribution fragment masses following fission, or fission yields, impacts many different applications including the estimation of decay heat in nuclear reactors, reactor-neutrino studies, radio-isotope production for medical applications, and stockpile stewardship. Determining the isotopes produced in fission can be done in a straightforward way by measuring the characteristic γ rays emitted during the β decay of fission products. However, much of the nuclear data on fission-product β decay contain high uncertainties, and we aim to improve these data to better inform applications and basic science. Using an experimental method that takes advantage of radioactive ions beam at the CARIBU facility and a very well characterized detection system at Texas A&M, we recently performed a measurement of the 111Ag isotope to a high degree of precision. We will present our branching ratio results and will also discuss future plans to continue these types of measurements at LLNL.
