摘要
Stark broadening parameters for 53 Ra II spectral lines have been calculated. Calculations have been performed within the frame of the modified semiempirical approach within the temperature range 5000-50000 K. Stark broadening parameters for 43 Ra II spectral lines have been calculated for an electron density of 10(20)m(-3), while Stark broadening parameters for 10 Ra II spectral lines, belonging 5f(2)F(o)-7d(2)D, 6d(2)D-7p(2)P(o) 7d(2)D-8p(2)P(o) and 8d(2)D-9p(2)P(o) Ra II multiplets in the far infrared, have been presented for an electron density of 10(20) m(-3). Results have been used for a discussion of Stark broadening regularities within multiplets and systematic trends along spectral series. Moreover, the results obtained have been compared with simple estimates based on regularities and systematic trends.
