 The data in this file are based on that of Zhang et al.(1990) with the following
 modifications to correct them for the effect of resonances and to increase or
 decrease their values to bring them into line with the close-coupling data as
 reviewed by McWhirter (ADNDT 1994). The parameters used for these modifications
 are listed below (see McW's review for an explanation of the symbols):
  1. Enhancement due to resonances following Bhadra and Henry (1982). Values of
 2s-3s    1.9
 2s-3p    2.8
 2p-3s    8.0
 2p-3p    4.0
 2. Correction factor by wich Zhang et al's values have been divided to bring
 them closer to the close-coupling results:
 2s-3s    1.0
 2s-3p    0.86
 2s-3d    1.0
 2p-3s    0.88
 2p-3p    1.12
 2p-3d    1.13
 The value of the ionization potential has been taken from Kelly's wavelength
 tables (J Phys Chem  Ref Data vol 16 Supp 1 1987)
 Where Zhang et al. have not provided data the table has been extended using
 the impact parameter approximation.
