Precise ⁹²Rb and ⁹⁶Y yields for thermal-neutron-induced fission of ²³⁵U and ^{239, 241}Pu determined using calorimetric low-temperature detectors

NUCLEAR REACTIONS ²³⁵U, ^239,241Pu(n, F), E=thermal neutrons from high-flux reactor at ILL-Grenoble; measured fission fragments using the LOHENGRIN mass spectrometer; deduced fractional independent yields per A=92 and A=96, independent yields per fission of A=92 and 96 isotopes of ⁹²Rb, ⁹²Sr, ⁹²Kr, ⁹⁶Rb, ⁹⁶Sr, ⁹⁶Y and ⁹⁶Zr, and cumulative yields. Comparison with previous experimental results, and with data in evaluated libraries: JENDL-4.0, JEFF-3.3, and ENDF/B-VIII.0, and with GEF theoretical calculations. Relevance to reducing nuclear data uncertainties in the computation of reactor antineutrino spectra by the summation method. Discussed problem of ⁹²Rb β^- decay to ⁹²Sr ground-state in the context of discrepancies between previous measurements for fission yields.
