        From a 41-state RMPS calculation that included the 9 spectroscopic   
        terms of the configurations 1s22s, 1s22p, 1s23s, 1s23p, 1s23d, 1s24s,
        1s24p, 1s24d, 1s24f; and the 32 pseudo states 1s2nl for n = 5 to 12  
        and l = 0 to 3 in the close-coupling expansion.                      
        The 1s and 2s orbitals were generated from a single-configuration    
        Hartree-Fock (SCHF) calculation on 1s22s, while the 2p through 4f    
        orbitals were generated from a SCHF calculation on the terms         
        1s2nl with the 1s orbital frozen.  The pseudo states were generated  
        from an non-orthogonal Laguerre basis; these states were then        
        orthogonalized with respect to the Hartree-Fock orbitals and each    
        For the L = 0 to 12 even and odd parity LSPI partial waves, we       
        performed an R-Matrix calculation with exchange.  For the higher     
        partial waves we performed a no-exchange R-Matrix calculation for    
        L = 13 to 60 with the long-range perturbations turned on and with    
        topup.  However, because of numerical problems for high partial waves
        that affected only the 2-4, 2-7, and 2-9 transitions, the NX run for 
        these three transitions was from L = 13 to L = 30, again with long-  
        range perturbations turned on and with topup. The continuum basis for
        these calculations was set to 40 and the radius of the R-matrix box  
        was 20.76 a.u.
