Electron Excitation of Atoms and the Stretched Atom States.

Abstract

In spite of its importance in atomic collisions, very little had been done in way of measurements of the cross sections for electron-impact excitation into the nF levels. The main reason is that in order to detect the atoms excited into the nF levels, one has to measure the radiations emitted by the nF atoms which are in the infrared, outside the spectral region covered by the conventionally used photomultiplier tubes. Since we have recently equipped our laboratory with the capabilities of Fourier Transform spectroscopy, we are in a position to measure the infrared radiations emitted by the nF atoms produced in an electron-beam experiment.
