Atomic transition probability ratios between some ArI 4s-4pand 4s-5ptransitions

All recent determinations of the atomic transition probabilities for the prominent ArI 4s-4p lines in the red part of the visible spectrum have been carried out separately from determinations of the equally prominent 4s-5p lines in the blue part of the spectrum. A cross connection of these data is thus desirable to establish their mutual consistency. We have measured several transition probability ratios for 4s-4p to 4s-5p transitions and find very close consistency.
