 Energy levels, radiative rates, dipole and Born limits were calculated using 
 AUTOSTRUCTURE with the following orbital scaling parameters: 
    1s : 1.44061 
    2s : 1.23211 
    2p : 1.16447 
    3s : 1.25727 
    3p : 1.20910 
    3d : 1.28700 
    4s : 1.25818 
    4p : 1.13628 
    4d : 1.28178 
    4f : 1.45048 
    5s : 1.23717 
    5p : 1.19547 
    5d : 1.24916 
    5f : 1.26429 
    5g : 1.16526 

 The exchange calculation was performed up to 2J = 23 (L = 0 to 14) 
 The non-exchange calculation was performed up to 2J = 77 (L = 10 to 42) 
 35 continuum basis oribtals were used, yielding a smallest maximum 
 basis-oribtal energy of 14.809 Ryd 
 z^2-scaled energy meshes: (start, end, step, points): 
     fex: 1.000000e-10, 1.568895e+00, 4.356832e-04, 3602 
     cex: 1.569891e+00, 3.000000e+00, 1.430109e-03, 1001 
     nex: 1.000000e-11, 3.001432e+00, 1.431981e-03, 2097 
 The energy mesh fex was used between the first and last thresholds 
 for the outer region exchange calculation. 
 The energy mesh cex was used between the last threshold and about 
 3 times the ionization potential for the outer region exchange calculation. 
 The energy mesh nex was used between the first threshold and about 
 3 times the ionization potential for the outer region non-exchange calculation. 
 Dipole and Born limits were used from the last calculated 
 energy point up to infinite to complete the effective collision strengths.
