------------------------------------------------------------------------------- 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 Unpublished 29 state R-matrix calculations of Berrington et al.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. H.P. Summers, June 1993 Update: Attention has been drawn to errors in some A-values in the dataset by Mathias Brix. The corrections are as follow: 15-14 trans. A-value 4.15E-05 -> 4.15E+03 17-15 trans. A-value 8.15E-10 -> 8.15E-02 19-13 trans. A-value 5.79E-04 -> 5.79E+04 19-16 trans. A-value 5.70E-07 -> 5.70E+01 18-16 trans. A-value 3.63E-10 -> 3.63E-02 The errors occurred in transcription from the Wiess, Smith, Glennon tables by Summers. These very small A-values have no impact on neutral helium population calculations. The following change has 9- 4 trans. A-value 7.08E+07 -> 7.06E+07 has also been made matching the NIST-DAS tabulation. H.P. Summers, 29 Jan. 1997 Update: A further revision of excitations from 2(3)S and 2(1)S has taken place in association with FOM-KVI (R. Hoekstra, F de Heer, F. Bliek) making use of converged close coupling calculations. The new data has replace the older data above where there is overlap. The new preferred cross-section data are archived as JETSHP.KVI.DATA(EXC#HE0D) The rate parameters are produced in ADF04 format by the code JETSHP.COPASE.FORT(NEUTQD2) H.P. Summers, 3 Feb. 1997 Update: An error in the 4(1F) and 4(3F) transitions from the 2(1S) and 2(3S) metastables has been detected by Mathias Brix. The 4(1F) and 4(3F) transition indices have been interchanged. The transitions affected are 17-2, 18-2, 17-3 and 18-3. A further statistical weight error was detected which means that the upsilon for the new 18-3 transition is 1/3 of the old 17-3 value. The corrections have been made. H.P.
