Scientific paper

This work reports an extensive collection of 108 transition probabilities of NII lines in the visible spectral region, all of them measured in an emission experiment. Relative intensity measurements have been made on a pulsed discharge lamp and the absolute Aki values have been obtained by using the literature available data. Electron density and temperature range in this experiment from 0.2 to 1.1 \ 1023 m-3 and from 17000 to 29000 K respectively. The first one has been simultaneously determined from two-wavelength interferometry and from the Stark broadening of HeI 471.3 nm, the second from Boltzmann-plot of NII lines and from NII/NI intensities ratios. The results are compared with the recent available literature.
