THE EXCITATION AND LUMINESCENCE MECHANISMS OF RARE GASES AND RARE GAS MIXTURES IN BOMBARDMENT WITH FAST ELECTRONS (in German)
In order to study the excitation and luminescence mechanisms of rare gases and rare gas mixtures in bombardment with fast electrons, the decay tinies of the luminescence and the spectra were investigated in dependence on the gas pressure. The decay time-pressure curves of the rare gases Ne, Ar, Kr, and Xe have a maximum. This suggests the same excitation niechanisni. The pressure dependence in He varies irregularly, probably because of the strong intercombination probibition. The maxima were reduced to step excitations over the metastable levels. By admixture of O/sub 2/ and N/sub 2/ the concentrations of the metastable rare gas atoms were decreased, the decay times were affected, and (especially by O/sub 2/) the continua were weakened. In Ne-Ar mixtures the decay-pressure curve shows that practically no excitation of Ar atoms results from collisions of the second type with Ne atoms. In Ar-Xe mixtures it is indicated that the excitation of Xe by collisions of the second type with metastable Ar atoms is of significance. The spectra of these mixtures contain two bands which were emitted probably by ArXe molecules. (tr-auth)
