Abstract

Using the semi-classical perturbation approach in the impact approximation, full width at half maximum and shift have been determined for eight spectral lines of Ar VII, for broadening by electron-, proton-, and He III-impacts. The results are provided for temperatures from 20,000 K to 500,000 K, and for an electron density of 10 18 cm 3 . The obtained results will be included in the STARK-B database, which is also in the virtual atomic and molecular data center (VAMDC). View Full-Text
