Oscillator strength, assessment

The interpretation of the intensities of lines observed in astrophysical sources requires a wide variety of reliable atomic and, to a lesser extent, molecular data [1]. Also, the steady development of high temperature plasmas, in relation to the fusion programmes ongoing in several countries, has given rise to a considerable interest in the spectroscopy ofheavy and/or highly ionised atoms [2], The spectacular advance of some experimental techniques has not diminished the need for reliable theoretical data. In the production of spectroscopic quantities such as oscillator strengths to fulfill the present demands of both the astrophysics and plasma physics communities, several authors [3-5] have emphasised the need for both experimentalists and theoreticians to self-assess the data they supply. 

Therefore, we have attempted to assess the correctness of our results by analysing their possible regular behaviour along the group. As an example, we have collected in Table 4 the RQDO oscillator strengths for a few multiplets that cor-... 

The assessment of the oscillator strengths for electronically allowed bands is quite straightforward all one need do is compute the transition dipole moment or transition probability, e[Pg.242]
