Experimentally obtained transition probabilities for some ultraviolet Kr II lines, expressed in absolute units, are presented in this paper. For the measurement, intensities of spectral lines emitted by a plasma generated in a low-pressure pulsed arc were used. The electron density was in the range of (1.5 - 3.4) × 1022 m−3, while the temperature was between 28 000 K and 35 000 K.
