Abstract

Tables are provided from which the local emissivities of spectrum lines arising from transitions between principal quantum shells of hydrogen-like and lithium-like ions in a plasma may be derived easily, subject to knowledge of the local plasma conditions and impurity ionisation stage abundances. It is assumed that the free electron distribution in the plasma is locally Maxwellian and that neutral hydrogen may be represented locally as a density. The bundled n picture, which assumes relative statistical populations of states corresponding to the same principal quantum number, is adopted. The selected tables presented cover ranges of electron temperature density, and neutral beam energy. A number of hydrogen- like and lithium-like ions are given and the tables are suitable for a general approximate survey. The theoretical basis of the calculations is outlined and attention drawn to the principal approximations involved. Tabulations in the resolved nl picture will be presented in the second paper in this series. The theory of both the bundled n and resolved nl pictures will be presented in detail in another work (Spence and Summers, 1985).
