Abstract

The ratio of line strengths for the two argon transitions, 3p⁵(²P_1/2^o)4s[1/2]₁^o\ensuremath→3p⁵(²P_3/2^o)4p[3/2]₂ at wavelength 922.7 nm and 3p⁵(²P_1/2^o)4s[1/2]₁^o\ensuremath→3p⁵(²P_3/2^o)4p[5/2]₂ at wavelength 978.7 nm, is measured in an argon pulsed discharge with the use of a single-mode Ti:sapphire laser. The result 3.29(0.13) is in agreement with our theoretical prediction 3.23 and with a less accurate ratio 2.89(0.43) from the NIST database.
