    • j, the estimates of the Doppler widths manifest errors due to the differences in the individual state's splittings. Peak fitting/analyses programs (Microcal ORIGIN) give reasonable error ranges for possible level splittings and populations. The final temperatures realistically depict the atom temperatures, which are constant in the source region.

    • 2, thus the radiation trapped atom density would also be proportional to the square of the neutral density (pressure). The pressure dependence in Fig. 5 fits well to a second order polynomial, supporting the possibility of radiation trapping for the resonant argon states here.
