Relative Transition Probabilities for Krypton

Relative transition probabilities of the more prominent Kr i and Kr ii lines have been measured using a gas-driven shock tube as a spectroscopic source. Results for 22 Kr i lines (4200 < λ < 8500 Å) and 33 Kr ii lines (4000< λ <5300 Å) have estimated reliabilities of 8–50%. The data are compared with other measurements and with theoretical calculations.
