• Spontaneous Emission: H⁺⁰(i) → H⁺⁰(j) + hv
• Electron Impact Excitation: H⁺⁰(i) + e → H⁺⁰(j) + e
• Free Electron Recombination: H⁺¹(i) + e → H⁺⁰(j)

  BACKGROUND  : THE DATA WAS OBTAINED BY FIRST SUBJECTING
                THE THE ADF04 FILE 'HPSL91H' TO ADAS211.
                ADAS211 ESSENTIALLY IMPLEMENTS THE BURGESS
                AND TULLY TRANSFORMATION ON THE EFFECTIVE COLLISION
                STRENGTH ( SEE REFERENCE (1)). THE X AND Y
                ARRAYS DESCRIBED IN (1) ARE THEN PASSED TO A
                SUBROUTINE WHICH PRODUCES A SPLINE THROUGH THE
                THE DATA.TO OBTAIN THE EFFECTIVE COLLISION STRENGTH
                FOR A GIVEN TEMPERATURE RANGE, ADAS211 READS THE
                REQUIRED TEMPERATURE RANGE AND THE CORRESPONDING
                Y VALUES ARE EVALUATED FROM THE SPLINE. THE NEW
                EFFECTIVE COLISION STRENGTH IS OBTAINED BY
                REVERSING THE TRANSFORMATION.

  Modified data for 1s-2s,2p,3s,3p,3d; 2s-3s,3p,3d; 2p-3s,3p,3d substituted
  based on analyis of Calloway recommendations (1994)ADNDT
  in combination with Sampson data.  Preferred curves were established using
  Burgess C-plots on EXCEL spreadsheets.

  Update : 17/03/99  H. Anderson
		      Identified and corrected the error associated with
		      the effective collision strength at 3.48E+04 K
		      for the transition H(2s)-H(3d) i.e. 6-2. The value
		      originally inserted into the file was 70.0 when it
		      should have been 7.0.

		      Corrected error associated with the effective
		      collision strength at 8.12E+04 K for the transition
		      H(1s)-H(3s) i.e 1-4. The value original entered
		      was 6.03E-04 when it should have been 9.10E-02.
		      Source of error was due to a mistake in the
		      excel spread sheet.

		      Corrected error associated with the data for the
		      transition H(2p)-H(3p) i.e. 5-3. The values for
		      at 5.8E5 and 1.16E6 K which were respectively
		      9.44-01 and  9.37-01 were incorrect. The correct
		      values are  2.53+01 2.68+01
