----------------------------------------------------------------------- A-values are taken from Wiese, Smith & Glennon NBS-NSRDS Dipole & non-dipole transitions from the 1(1)S follow (i) preferred curves from comparative graphs up to the n=4 shell strongly influenced by experiments of Westerfeld (1979) J. Phys. B. 12,115 Van Zyl et al.(1980) Phys. Rev. A22, 1916 Heddle & Gallagher (1989) Rev.Mod.Phys. 61, 221, Born limits and to a lesser extent by Fujimoto (1978) IPPJ-AM-9. Unpublished 29 state R-matrix calculations of Berrington et al. (1990) have been used in association with Heddle & Gallagher to correct the low temp values up to 10eV of 1(1)S - 3(1)D, 1(1)S - 3(1)P Dipole & non-dipole transitions from the 2(1)S & 2(3)S states follow (i) Fujimoto (1978) IPPJ-AM-8. Non-dipole Born limits from Flannery, Morrision & Richmond (1975) J.Appl.Phys. 46, 1186 Dipole transitions within the n=3,4 shells (i) Impact parameter approximation Spin change data follow (i) Kato (1989) At. Data & Nucl. Data Tables 42,313 for transitions 1(1)S - 2(3)S and 1(1)S - 2(3)P (ii) Berrington et al. (1985) J. Phys. B. 18, 4147 for transitions 2(3)S - 2(1)S, 2(3)S - 2(1)P, 2(1)S - 2(3)P & 2(3)P - 2(1)P at low temperature and follows a similar decay to high temperature as the Kato data (iii) For 1(1)S - 3(3)L , the data of Berrington et al. is used for low temperature and then the shape of the Kato curves above 5eV scaled to match Berrington at 5eV. (iv) For 1(1)S - 4(3)L , 1/n**3 scaling is used from the n=3 data. H.P. Summers, Mar. 1991 Update: Dipole transitions between 2(1)P - n=3,4 and 2(3)P - n=3,4 added. (i) Impact parameter approximation H.P. Summers, Jan. 1992 Update: A complete revision of excitations from 1(1)S and 2(3)S, 2(1)S has taken place in association with FOM-KVI (R. Hoekstra, F de Heer, H-F Folkerts) making use also of recent Belfast R-matrix data. The new data has replace the older data above where there is ovelap. The new preferred cross-section data is archived as JETSHP.KVI.DATA(EXC#HE0A) - excitation from 1(1)S JETSHP.KVI.DATA(EXC#HE0B) - excitation from 2(1)S, 2(3)S The rate parameters are produced in ADF04 format by the codes JETSHP.COPASE.FORT(NEUTQUAD) and JETSHP.COPASE.FORT(NEUTQD2) respectively.
