       From a 19 term, 31 level Intermediate Coupling Frame Transformation
       (ICFT) R-matrix calculation that includes the terms of the
       configurations 1s2, 1s2s, 1s2p, 1s3s, 1s3p, 1s3d, 1s4s, 1s4p, 1s4d,
       and 1s4f.  For the scattering calculations, the 1s orbital was
       generated from a Hartree-Fock (HF) calculation on 1s2 while the
       remaining nl orbitals were generated from HF calculations on the
       1snl configurations.

       For the JPI partial waves from J=0.5 to 12.5 with both even and odd
       parity, we performed an LS R-matrix calculation with exchange on the
       LSPI partial waves from L = 0 to 14 and then transformed the
       unphysical K-matrices to intermediate coupling using the ICFT method.
       For the higher partial-wave contributions from J = 13.5 to J = 58.5,
       we performed a no-exchange R-matrix calculation in LS coupling for all
       partial waves from L = 12 to 60.  The size of the continuum basis for
       these calculations was set at 50 and the R-matrix "box" had a radius
       of 6.618 a.u.  The asymptotic part of the calculation was carried out
       up to an energy of 300 Ry.

       The electric-dipole radiative rates were generated from a Breit-Pauli
       configuration-interaction calculation in which pseudo states were used
       to correct the 2p orbital in the 1s2p 1P term and the 3p orbital in
       the 1s3p 1P term for term dependence.  In addition, in the radiative
       rate calculations only, the 1s orbital was calculated from the
       1s2p 3P term and then the 1s orbital in 1s2 1S term was corrected by
       including a pseudo state minimized on 1s2 1S.

       E1 transitions from MCHF Froese Fischer code.
       Radiative transition rates include E2,M1 and M2 transitions,
       from a fully relativistic calculation (HULLAC).
       Including two-photon transition 1s2s ^1S_0 --> 1s^2 (6-1),
       from A. Derevianko and W.R. Johnson, PRA 56, 1288 (1997).
       Some transitions (2-1, 4-1, 7-1, 5-2, 4-2, 3-2, 7-2, 7-6)
       have been updated from W.R. Johnson et al.,
       Adv. At. Mol. Opt. Phys. 35, 255 (1995).

       Including also radiative recombination from the H-like 1s level,
       and dielectronic recombination via 2snl and 2pnl (n=2,5)
       intermediate autoionizing levels (with cascades). (AutoStructure).
       IMPORTANT: The quantities given in this file are the RATES, and
         ADAS needs G*RATES (i.e. multiplied by the statistical weight).
         Therefore, if ADAS is used, the input ratio NH/NHe has to be
         multiplied by G(1s)=2.
