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

  BACKGROUND  : THE DATA WAS OBTAINED BY FIRST SUBJECTING
                THE THE ADF04 FILE 'HPSH91H' 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:  28/08/97  HP Summers - checked energy levels - OK.


  Update:  18/03/99  H. Anderson

		      Identified and corrected the error associated with
		      the effective collision strengths for the transition
		      H(2p)->H(3p) for the following temperatures:
		
 		      5.80+05  1.16+06  2.32+06  5.80+06  1.16+07 2.32+07 
		      5.80+07  1.16+08  2.32+08  5.80+08  8.12+08

		      Source of error was idenitied to be due to a
		      mistake in the excel spread sheet used to 
		      prepare the data.
