Measurement of several transition probabilities in singly-ionized krypton

This work reports a collection of 35 transition probabilities of lines in t he spectral region 450-580 nm, all of them measured in an emission experime nt. Relative intensity measurements have been made in a pulsed discharge la mp and the absolute A(ki) values have been obtained by using reference data taken from the literature. The electron density has been determined by two -wavelength interferometry and ranges from 0.1 to 0.8 x 10(23) m(-3) in the plasma. Temperature (14 000-24 000 K) has been simultaneously determined f rom three different methods, including the Boltzmann-plot of KrII lines and the KrII/KrI intensities ratios. The final results have been compared with most of the previous existing data.
