Paper Abstract

The results of a 345.1 nm line excitation mechanism investigation are presented. A comprehensive analysis of the radiative transition rates for the B+ lower energy levels is carried out. The rate constants of the electron impact excitation/de-excitation processes involved are also calculated. These fundamental data are used in a collisional-radiative model that results in the steady-state B+ level population. An important feature of the model is taking into account a ladder excitation mechanism through the metastable level 2s2p3Po by electron impact. This mechanism strongly changes the dependences of the level populations (and line intensities) on the plasma electron temperature. A dependence of the intensity ratio at 345.1 nm and 162.4 nm on the plasma electron temperature is also presented which can be used for plasma diagnostics.
