The radiations emitted by ²³⁹₉₂U, and its formation in the deuteron bombardment of uranium

Abstract

The production of ²³⁹₉₂U by deuteron bombardment of uranium has been established and the radiations of this product have been examined by the absorption method. The normal mode of disintegration involves β -particles having an upper energy limit of 1.20 ± 0.02 MeV. and a low-energy γ -ray of 76 ± 3 keV. quantum energy. Evidence has been found for electrons of less energy (about 0.1 per disintegration) and more penetrating γ -rays of relatively low intensity. Quantum radiations corresponding broadly to the L X-radiations, to be expected to follow the internal absorption of the low-energy γ -ray, have also been detected. The excitation function for the process ²³⁸₉₂U (²₁H, ¹₁H) ²³⁹₉₂U has been studied, and the conclusion reached that the Oppenheimer-Phillips mechanism is responsible for the larger part of the yield.
