  Collision strengths :

   %filename: si_9.splups
   %oscillator strengths: Bhatia, A.K., Doschek, G.A., 1993, ADNDT, 55, 281
   %collision strengths: Bhatia, A.K., Doschek, G.A., 1993, ADNDT, 55, 281
   %effective collision strengths (ground configuration): Aggarwal, K.M., 1983, J.Phys.B, 16, L59
   %comment: Relativistic effects are not included in the Aggarwal calculations, but he
      does a comparison with the DW calcs of Mason & Bhatia (MNRAS 184, 423,
      1978) and finds good agreement. A comparison with the more recent Iron
      Project data of Lennon & Burke (AAS 103, 273, 1994) also shows good
      agreement.
   %comment: As Aggarwal did not present calculated energies, observed values have been used.
   %comment: effective collision strengths were provided in the temperature range 5.5 < Log T < 6.4
