Performance tests were carried out on a circuit designed to distinguish between recoil electrons and recoil protons, due to incident photons and neutrons, respectively, in a hydrogenous scintillator. The activities produced in lutetium foils by irradiation were found to be a function of thickness. Data are presented for correction of lutetium activity measurements from thick foils to that for thin foils. Subcritical experiments with 1.82 wt % Pu-Al rods in light water were conducted. A series of criticality experiments were begun with plutonium-nitrate solutions in a 14-in. diameter stainless steel sphere fully reflected with water. Monte Carlo calculations were made of the limiting critical concentration of Pu²³⁹ and U²³⁵ in aqueous solutions. (M.C.G.)
