The aim of this work is to provide Stark parameters of low intensity Xe II and Xe III spectral lines from which scarce or null previous information exist.This work completes the measurements of ionized Xenon parameters developed in the last few years and extends Stark parameters database for astrophysical applications. All Stark parameters were measured in a pulsed arc plasma with 95% of helium and 5% of xenon. Measured electron densities and temperatures were in the range of (0.2-1.7)x10²³m^–3 and 18000-25500K, respectively. As a whole 25 Stark widths and 29 shifts of XeII spectral lines have been measured, along with 10 Stark widths and 6 shifts of Xe III. Some of the presented data are compared to theoretical values calculated using modified semiempirical formulae, as well as to other available experimental results.
