Radiative Lifetimes of Ultraviolet Emission Systems Excited in BF3, CF4, and SiF4

Abstract
Radiative lifetimes in the range 2 to 11 nsec have been measured by the phase‐shift method of Lawrence for four extensive near‐ and vacuum‐ultraviolet emission systems excited by 200‐V electrons in low‐pressure BF3, CF4, and SiF4 gases. With the possible exception of the system excited in BF3, the systems appear continuous under 0.4−Å resolution and all are probably due to polyatomic emitters. Electron excitation spectra of several other gases are briefly described.
