  Photoionization cross sections and recombination rate coefficients are
presented for the L-shell ground state fine structure levels $2s^22p^4 \
^3P_{2,0,1}$ of Fe~XIX. Several sets of calculations including relativistic
effects are carried out: (i) Breit-Pauli R-matrix (BPRM), (ii) Relativistic
Distorted Wave (RDW), and (iii) a semi-relativistic calculation.
Non-relativistic LS coupling calculations are also done for comparison. The
BPRM calculations employ a configuration interaction target representation for
Fe~XX consisting of 12 LS terms (23-fine structure levels), as in the recently
reported BPRM calculations by Donnelly et al (MNRAS, 307, 595, 1999). The
background cross sections in all three sets of present calculations agree with
one another, but differ considerably from those of Donnelly et al. Owing to
much more extensive resonance structures in the present BPRM calculations, the
sum of the corresponding recombination rate coefficients for the $^3P_{2,0,1}$
levels are up to 50% higher than the LS rates at low temperarures but
comparable for higher temperatures; in contrast to the results of Donnelly et
al who obtained the LS rates to be higher than their BPRM results by about a
factor of 2. Reasons for these discrepancies are discussed.
