Abstract
A spectroscopic study of a helium-hydrogen afterglow plasma in a pulsed discharge hollow-cathode has been made to determine the energy transfer process which results in a population inversion in atomic hydrogen. Time-resolved emission measurements were made for the Balmer series in hydrogen and self-absorption measurements with lambda 3889 A (2s 3S - 3p 3P) and lambda 4650 A (2s 3sigma - 3p 3n) of helium were taken to monitor the metastable populations. Observations were made as a function of impurity concentration and as a function of helium pressure. The energy transfer from the 3S atomic metastables appears highly probable with only a minor contribution from the 3sigma molecular metastables.
