• Electron Impact Excitation: O⁺⁵(i) + e → O⁺⁵(j) + e

   The data in this file are based on that of Zhang et al.(1990) with 
   the following modifications to correct them for the effect of resonances 
   and to increase or decrease their values to bring them into line with 
   the close-coupling data as reviewed by McWhirter (ADNDT 1994). The 
   parameters used for these modifications are listed below (see McW's  
   review for an explanation of the symbols):
 
   1. Enhancement due to resonances following Bhadra and Henry (1982). 
   Values of alpha:
   2s-3s    1.7
   2s-3p    2.8
   2p-3s    5.0
   2p-3p    3.7
 
   2. Correction factors by which Zhang et al's values have been divided to 
   bring them closer to the close-coupling results:
   2s-3s    1.0
   2s-3p    0.75
   2s-3d    1.0
   2p-3s    0.75
   2p-3p    1.10
   2p-3d    1.09
 
   The value of the ionization potential has been taken from Kelly's wavelength
   tables (J Phys Chem  Ref Data vol 16 Supp 1 1987)
 
   Where Zhang et al. have not provided data the table has been extended using
   the impact parameter approximation.

            Above comments by RWP McWhirter circa Nov. 1995

            Energy levels and ionisation potential updated
            ref: C E Moore  "Tables of Spectra of H,C,N and O atoms and ions." 
            ed. by J W Gallagher, CRC Pres 1993
    
   Update:  21 Sept 98  J Lang
            Note energy levels used are the same as NIST Standard Ref Database
            61, NIST Database for Atomic Spectrocopy Version 1.0 apart from
            trivial differences viz 4f 2F3.5 is 0.5 cm-1 higher in NIST
                                    5f 2F2.5,3.5 are 5 cm-1 lower in NIST
                                    5g 2G3.5,4.5 are 5 cm-1 higher in NIST 

            A values updated to use Wiese, Fuhr and Deters 'Atomic Transition
            Probabilities of Carbon, Nitrogen and Oxygen, A critical Data Compilation'
            J Phys Chem Ref Data Mono 7, 1996. Where data not given resolved
            they were split using usual rules.
            
            Note that 4f -5g ie 14-23 and 15-23 and 15-24 remained as original
            data as no A values in Wiese et al. 
            Note no 5f-5g transitions, 21-23,22-23,22-24, as all these levels
            have the same energy. Changing to NIST energies would move 5f and 5g 
            10 cm-1 apart. 
            Allowed transitions involving 5g levels have no fill in data. 
            The fill-in data effective collision strengths were obtained from 
            Impact Parameter program using original energies and A Values.
