          J. Phys. B 32 2139-52 and 4129 for a more complete                
          description.                                                         
                                                                          
     From a 45-level Breit-Pauli R-Matrix close-coupling calculation.          
     The 1s, 2s, 2p, and 3s orbital were determined from a configuration-      
     average Hartree-Fock (CAHF) calculation on 3s2.  The 3p, 3d, 4s, 4p,      
     and 4d orbitals were determined from CAHF calculations on 3s3p, 3s3d,     
     3s4s, 3s4p, and 3s4d configurations.                                      
                                                                               
     For the JPI partial waves from J = 0.5 to 10.5 and even and odd parity,   
     we performed an R-matrix calculation with exchange.  Then for the higher  
     partial waves, we performed a no-exchange calculation in LS coupling      
     for all LSPI partial waves with L = 10 to 60 (PERT='YES'),transformed     
     the K-matrices to intermediate-coupling, and topped up.  This allowed us  
     to add the partial-wave contributions from J = 11.5 to 58.5.  The size    
     of the continuum basis for these calculations was set to 25.  The         
     maximum energy in the R-matrix calculations was 2177 eV (160 Ry). The     
     radiative rates for the dipole-allowed transitions were determined from   
     our 45-level CI calculation in the Breit-Pauli approximation.

     The numbers in the last column of the above table are the theoretical
     values for the reduced effective collision strengths in the infinite
     temperature limit as defined in Burgess and Tully Astron. Astrophys.
     254 436 (1992).
