Abstract:

The paper presents observations of both dipole and quadrupole resonance spectra made on several discharge tubes with column radii ranging from 0.30 to 0.87 cm. For these measurements the value column radiusDeby length varies from about 1000 to 1000000, and the best fit electron temperatures are found to be of the order of 3 ev. The average electron densities were directly measured using a cavity perturbation technique. The results of these observations were found to be in good agreement with the theory based upon the first two moments of the correlationless Boltzmann equation in conjunction with Parkers electron density profile for a low density positive column. The results of a preliminary investigation of the effects of an axial, static magnetic field on the dipole resonance spectrum are also presented. These results indicate that in the presence of an axial magnetic field not only does the lowest resonance approximately predicted by the cold plasma theory split, but the next higher order resonance also splits.
