Impact of Modular Total Absorption Spectrometer measurements of β decay of fission products on the decay heat and reactor ν(bar)_e flux calculation

RADIOACTIVITY ⁸⁶Br, ^89,90Kr, ^89,90,92Rb, ¹³⁹Xe, ¹⁴²Cs(β^-) [from ²³⁸U(p, X), E=40 MeV]; measured decay products, Eγ, Iγ, Eβ, Iβ; deduced a substantial increase in β feeding to high excited states in all daughter isotopes in comparison to earlier data, reduction of the reference reactor ν-bar flux.
