摘要: Absorption line profiles of neutral argon spectral lines have been investigated using a GaAlAs diode laser as light source. The broadening and the shift coefficients for 811.5 nm line, which terminates on lowest metastable state 1s5, values (1.42+or-0.14)*10-20 (4.4+or-0.4)*10-21 cm-1 cm3, respectively. From 810.4 840.8 lines, terminate resonance states 1s4 1s2, oscillator strengths transitions at 106.7 104.8 determined to be (49+or-5)*10-3 (207+or-20)*10-3, coefficient was about half value no observed in accordance with theory Lewis (1967).
