On the Stark broadening of the Re II spectral lines

Stark broadening parameters - full widths at half maximum (FWHM) and shifts for 11 Re II lines have been calculated. The plasma parameters used were electron density of 1017 cm−3 and temperature from 5000 K to 80000 K. Calculations were performed using the simplified modified semiempirical (SMSE) ap...

Summary:Stark broadening parameters - full widths at half maximum (FWHM) and shifts for 11 Re II lines have been calculated. The plasma parameters used were electron density of 1017 cm−3 and temperature from 5000 K to 80000 K. Calculations were performed using the simplified modified semiempirical (SMSE) approach and compared with calculations by Cowley’s approximative Stark broadening formula at 10000 K, usefull in spectrum synthesis. The results have also been considered in the atmosphere model of A type star and for DB white dwarfs.
