3. ADAS703 Postprocessor Autostructure gt adf04 file Figure 8 3 The program isolates energy level Auger rate and radiative rate data from ADAS701 calculations It assembles these into specific ion files of type adf04 which include data lines for energy levels of doubly excited states and data lines for free bound resonance capture and Auger break up These specific ion files are the precursors for doubly excited population calculation and dielectronic satellite line emissivity prediction Only specific ion files in intermediate coupling J resolution may be created Supplementary electron impact re distributive collision data in a simple impact parameter approximation are also produced and added to the adf04 file Background theory Within ADAS calculation of the population structure of excited states of an ion in a plasma has previously been restricted to bound states or to states which are uncoupled to continua in which they are embedded This has prevented explicit calculation of the populations of doubly excited states which participate in dielectronic recombination or excitation auto ionisation The ADAS population code ADAS705 releases this contraint by allowing inclusion of resonance capture coefficients Auger break up rates and inner shell excitation rate coefficients in its rate equations In practice such data must be provided in the input specific ion file of data format adf04 upon which ADAS705 works The doubly excited states
