Zero-field quantum beats were observed in the Hβ emission (4 861 Å) from hydrogen atoms formed by beam-foil interaction of 110 to 250 kev proton beams. The energy dependence of the relative...

Étude d'une source émanante (production de radon) (1964)

Singer, W.

Le comportement d'une source émanante solide de 50 mCi — précipité de RaCO3 sur du Fe(OH3) — est comparé à celui d'une solution acide de RaBr2. Le rendement de cette source s'est...
