Electron-probe microanalysis of plutonium-base alloys

Description
The plutonium base samples are prepared according to Scott's method: decontamination, deposition of a formvar film, introduction in the microprobe. L and M emission spectra are determined by rotating a quartz-crystal on the Rowland circle and recording X - intensity versus wavelength. A 99 weight per cent Pu-Al alloy, easier to decontaminate than pure Pu (slow oxidation) was the chosen standard. In the end, absorption coefficients were calculated by Jonsson's method. (authors)

Les echantillons a base de plutonium sont prepares suivant la methode decrite par SCOTT: decontamination, depot d'une pellicule de formvar protectrice, introduction dans le microanalyseur. Les spectres d'emission L et M sont determines par enregistrement de l'intensite X en fonction de la longueur d'onde par rotation du cristal de quartz analyseur sur le cercle de Rowland. Le choix d'un etalon de reference s'est fait sur un alliage Pu-Al 99 pour cent en poids en raison de sa decontamination aisee (oxydation lente) pour une forte teneur en Pu. Enfin les coefficients d'absorption sont calcules par la methode de JONSSON. (auteurs)Files
