Catalog Service: IRON Project XLII. Fe XXI
Description
Effective collision strengths for transitions between 52 fine structure states calculated in a Breit-Pauli approximation are provided in ups.dat. Results are provided for logT in the range of 3.0-7.4 in steps of 0.1. The level indices refer to the ordering given in Table 2 text where the energies are also given. The format is most easily described by the fortran program provided - readups.f - which may be used to interface with user programs. Oscillator strengths for all dipole allowed transitions are provided in osc.dat which are also indexed with respect to Table 2.
