------------------------------------------------------------------------------- 31 LEVEL RADIATION-DAMPED ICFT R-MATRIX CALCULATION FOR AR+16. Overview: Results are from a 31 level intermediate coupling frame transformation R-matrix calculation including resonance effects and radiation damping for helium-like argon. Reference: A D Whiteford N R Badnell C P Ballance M G O'Mullane H P Summers A L Thomas J Phys B 34 3179--3191 (2001) A radiation-damped R-matrix approach to the electron- impact excitation of helium-like ions for diagnostic application to fusion and astrophysical plasmas. Level energies: The level energies are theoretical, computed by an AUTOSTRUCTURE calculation. They have not been altered to best theoretical values. For precision see referenced paper. Transition Probabilities: These are theoretical, computed by AUTOSTRUCTURE. They include electric dipole, electric quadropole and magnetic dipole values. These data are consistent with the cross-section calculations. For precision see referenced paper. For correct collision-radiative modelling one must include the two photon decay process from 1s2s 1S0 to 1s2 1S0, i.e. the 5-1 transition. This can safely be modelled as a radiative rate but no such rate has been included. Rate coefficients: Detailed attention has been given to the high energy behaviour of the collision strengths as they approach their limiting values, calculated by AUTOSTRUCTURE. At low energies, the resonance structure was resolved sufficiently to calculate rate coefficients down to 3E5 K. For more details see the referenced paper. Errors of around 20% are expected for the 3E5--3E8 temperature range with lesser errors for some transitions (notably the dipoles).
