   Energy levels
   Taken from NSRDS NBS 3 Sect 3.

   Ionisation Potential
   As energy levels. Note Kelly (J Chem Phy Ref Data 16, 1987) has same
   value.

   Transition Probabilities
   For allowed transitions are from Fawcett (At Dat and Nucl Data Tables
   30, 423, 1984) while for the intercombination 1-2 transition the result
   of Nussbaumer and Storey Ast and Ast 64, 139, 1978 was used.

   Collision Data
   Effective collision strengths for 2-2 transitions were from the
   results of Berrington (J Phys B 18, L397, 1985) with the actual data
   from the Belfast Daresbury Data Bank. For 2-3 and 3-3 transitions
   the results of Berrington et al (J Phys B, 22, 665, 1989) were used.
   The same 12 state R-matrix calculation was used for both papers.
   To overcome difficulties in obtaining converged cross sections
   involving the  n=3 states a new no exchange R matrix package was
   used for L>=11 in addition to the standard R matrix package.
   Partial wave contributions up to total angular momentum L  35
   had to be included before the Burgess sum rule could be used.

  Radiative recombination data is prepared using code

           JETSHP.DLS.FORT(ADASRRC)     on dataset
           JETSHP.RADREC.LILIKE(C3LS)

  H P Summers  15 July 1992.

     Dielectronic data is post-processed from Badnell files as follows:

          /JETSHP.BADNELL.LILIKE(C3LS12)
          /JETSHP.BADNELL.LILIKE(C3LS22)
          /JETSHP.BADNELL.LILIKE(C3LS23)

     The cross-referencing file is as follows:

          /JETSHP.BADNELL.XREFDAT(C2L)

     The parent metastable indices are as follows:

     1.    1S2 2S1             (2)0( 0.5)

     Dielectronic data added to  14 existing rad. recom. level sets
