Abstract: | For a representative set of atmospheric and atomic parameters we determine the strengths of solar dielectronic recombination lines originating in ions with Z 6 at frequencies of 70 GHz. We compare the line strengths derived here with those calculated by Berger and Simon (1972) and find that our values for representative ions with Z 3 are lower by a factor 102–103, being mainly the result of the inclusion of the electronic pressure broadening. We outline the requirements for the detection of lines, which must establish an upper limit of at least 10-5 for the line to continuum ratio. |
