This work reports measurements of nine Stark widths and nine Stark shifts of Xe II spectral lines. These line parameters have been measured in a pulsed arc plasma in electron density and temperature range (0.2-1.6) X 1023 m-3 and (18 000-25 000) K, respectively. The results are compared to other experimental data as well as with theoretical values calculated from modified semiempirical formulae. Stark parameters of the lines belonging to the same multiplet are usually very close. The results obtained in this work show that in some cases very clear intramultiplet irregularities exist. These measurements, as well as some results from the previous works of this group, have been used to analyse the origin of these irregularities.
