| Description | Journal: Journal of Physics B: Atomic and Molecular Physics Absorption line profiles of neutral argon spectral lines have been investigated using a GaAlAs diode laser as a light source. The broadening and the shift coefficients for the 811.5 nm line, which terminates on the lowest metastable state $1s_{5}$, have the values $(1.42+or-0.14)*10^{-20}$ and $(4.4+or-0.4)*10^{-21}$ $cm^{-1}$ $cm^{3}$, respectively. From the broadening coefficients for the 810.4 and 840.8 nm lines, which terminate on the resonance states $1s_{4}$ and $1s_{2}$, the oscillator strengths for the resonance transitions at 106.7 and 104.8 nm have been determined to be $(49+or-5)*10^{-3}$ and $(207+or-20)*10^{-3}$, respectively. The shift coefficient for the 810.4 nm line was about a half of the value for the 811.5 nm line and no shift was observed for the 840.8 nm line in accordance with the theory of Lewis (1967). |
