Unfortunately these were over three temperature ranges and two resolutions so a degree of extrapolation with ADAS215 was required. The allowed electric dipole transitions were only given in LS resolution; these were unbundled with ADAS210. See above comments for details. K M Aggarwal, Astro. J. Suppl. 54, p1-15, 1984 K M Aggarwal, Astro. J. Suppl. 58, p289-296, 1985 K M Aggarwal, Astro. J. Suppl. 61, p699-717, 1986 The A-values are those of Aggarwal supplemented by those of A K Bathia and G A Doschek, ADNDT, 55, p315-348, 1993. Note that there is some disagreement in the A values between these papers, sometimes up to a factor of 2. It was decided to adopt the A value from the same calculation of the collision strength where this was available. Also note that there is some dispute in the literature regarding the accuracy of the Aggarwal allowed collision strengths (cf Burgess, Mason and Tully, Astro. J. 376, p803-808, 1991) Martin O'Mullane 4/10/98 ------------------------------------------------------------------------------- Energy levels from NIST data up to n=3. Levels 19 and 20 from 1s2 2p4 were not available. Comparison of the Cowan values and other theoretical calculations reported in Aggarwal AJ Sup. Ser. 118:589-602, 1998 do not give a compelling reason for replacing the Cowan values with the others. There is very littles NIST data for the n=4 levels and what is there is term averaged and not from observation. Therefore the Cowan values are preferred.

In addition the remaining levels of 2s2p23p and 2s2p23d and all the levels of 2p33s, 2p33p, and 2p33d were included in the CI expansion. The 1s, 2s, and 2p orbitals were determined from a single-configuration Hartree-Fock calculation on 2s22p2 3P. The 3s, 3p, and 3d orbitals were determined from multi-configuration Hartree-Fock calculations on 2s22p3s+2P33s 3P, 2s22p3p+2p33p 3D, and 2s22p3d+2p33d 3F, respectively, and the 4s, 4p, and 4d orbitals were determined from single-configuration Hartree-Fock calculations on 1s22p4l. In STG3 of the R-matrix calculation, the term energies were adjusted to the experimental term energies and in the ICFT calculation, the level energies were adjusted to the experimental values where known. For the JPI partial waves from J=0.5 to 9.5 and even and odd parity, we performed an LS R-matrix calculation with exchange for the LSPI partial waves with L = 0 to L = 12 and then transformed the unphysical K-matrices to intermediate coupling using the ICFT method. For the higher partial waves, we performed a no-exchange calculation in LS coupling, with the long-range multipoles included, for all LSPI partial waves from L = 8 to 40; transformed the unphysical K-matrices to intermediate-coupling; and topped up. This allowed us to add the partial-wave contributions from J = 10.5 to 37.5. The size of the continuum basis for these calculations was set to 24. The radiative rates for the dipole-allowed transitions were determined from our 138-level CI calculation in the Breit-Pauli approximation. The number of mesh points used in the asymptotic part of the problem was 8740 and the maximum energy was 15 Ry. Donald C. Griffin Published in J. Phys.
