Structures dans l'Emission Photonique de He Provoquée par Bombardement d'Electrons Monocinétiques dans la Région de 60 eV

Abstract

By measuring the photon intensity emitted by He excited by electron impact in the 60 eV region as a function of the electron energy, with an apparatus capable of excellent signal to noise ratio and energy resolution, several structures have been observed, some being entirely new and attributed to levels of the negative He⁻ ion.
