Abstract :
The optical properties and normal, spectral emissivity of liquid plutonium at 632.8 nm were measured over a temperature range of 2016–2189 K using rotating analyzer ellipsometry. The purity of the liquid was maintained in a containerless environment using electromagnetic levitation and heating. The material investigated contained 1 wt% Ga that was added during the casting process. The measured values of the optical property results are given as a function of temperature by ϵλ=5.38×10−5T+0.250, nλ=−1.29×10−4T+3.82, and kλ=−7.04×10−4T+5.77 over the investigated temperature range.
