----------------------------------------------------------------------- This file tabulates the collision strengths on a fairly standard grid, however care should be taken when using this ADF04 type 1 file, and any other type 1 file, because the tabulation may not be fine enough to form a well defined convolution with the distribution function being used. More information on this can be obtained from the compiler of this data set. This data incorporates the neutral helium R-matrix calculation of Ballance (2003). This calculation included detailed representation of the resonance region. Interval averaging techniques were used to convert the OMEGA file produced by the R-matrix calculation to a manageable size (Paton, 2003). The main differences between this data and previous ADAS preferred data lies at low energy. This data comprises components from the following workbooks (1) he0_excitation_1s(1S)-nl().xls (2) he0_excitation_2s(3S)-nl().xls (3) he0_excitation_2s(1S)-nl().xls (4) he0_excitation_2p(1P)-nl().xls (5) he0_excitation_2p(3P)-nl().xls (6) he0_excitation_3s(1S)-nl().xls (7) he0_excitation_3s(3S)-nl().xls (8) he0_excitation_3p(1P)-nl().xls (9) he0_excitation_3p(3P)-nl().xls (10) he0_excitation_3d(1D)-nl().xls (11) he0_excitation_3d(3D)-nl().xls (12) he0_excitation_4s(1S)-nl().xls (13) he0_excitation_4s(3S)-nl().xls (14) he0_excitation_4p(3P)-nl().xls (15) he0_excitation_4d(1D)-nl().xls (16) he0_excitation_4d(3D)-nl().xls (17) he0_excitation_4f(1F)-nl().xls (18) he0_excitation_4f(3F)-nl().xls (19) he0_ionisation.xls The workbooks contain historic comparative assessments of helium data and ADAS preferred data sets. The workbooks are available to identified data assessors for further study. Compiler: I. D.
