Production de vapeur d’uranium par pulvérisation cathodique dans une cathode creuse: efficacités relatives des gaz Ne, Ar, Kr et concentration à l’état ^5L60

We have investigated the production of uranium vapors in the ${}^5{L}_6^0$ ground state using a sputtering technique. We have also compared the performance of the Ne, Ar, Kr gases as carrier agents. We have found that the krypton gas gives a maximum yield with minimum energy. Finally the density of U vapors has been found to be of the order of 10¹² atoms cm⁻³.
