Abstract

Electric and magnetic fields cause splitting of energy levels in an atom. Transition of electrons among these levels could be seen as broadening and shift of spectral lines. We recognize various types of effects, the most important is Stark effect. We developed a program for calculations of temperature dependence linear coefficients of Stark broadening and shift of spectral lines. Our results were calcutated for temperatures usual for SF6 circuit breaker.
