Abstract

This work reports an extensive collection of 108 transition probabilities of NII lines in the visible spec- tral region, all of them measured in an emission experi- ment. Relative intensity measurements have been made on a pulsed discharge lamp and the absolute Aki val- ues have been obtained by using the literature available data. Electron density and temperature range in this ex- periment from 0: 2t o 1: 11 0 23 m 3 and from 17000 to 29000 K respectively. The rst one has been simultane- ously 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 in- tensities ratios. The results are compared with the recent available literature.
