Description
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.
