      INFORMATION                              #1989 RESTRUCTURED DATA
      -----------
      THE FOLLOWING OPTIONS ARE AVAILABLE SELECTED BY IBLOCK

      IBLOCK = 4
      ----------
      ENERGY    = 1 _ 1000 KEV/AMU
      N         = 1 _ 4
      APPROX    = BEST CHOICE FROM SEVERAL SOURCES (THEORY/EXPERIMENT)
      REFERENCE = LUDDE & DREIZLER, KIMURA & THORSON, WINTER & LIN,
                  SHAKESHAFT, FRITSCH, RYUFUKU.

      REMARKS:
      THE DATASET IS OBTAINED BY MANUALLY FITTING CURVES THROUGH
      N - SHELL FRACTIONAL CROSS-SECTION DATA.

      ALL DATA SOURCES WERE
      ANALYSED USING NEUTBEAM.FORT(CXERROR) CODE.  PLOTS OF ALPHA
      AND ITS APPARENT UNCERTAINTIES WERE PREPARED AND A PREFERRED
      ALPHA CURVE DRAWN MANUALLY. THIS ANALYSIS WAS ALSO USED TO
      DEDUCE A PREFERRED N=3,4 X-SECTS.  PREFERRED N-SHELL FRACTIONS
      WERE RENORMALISED USING ALPHA ONWARD FROM THE N=3 SHELL AND
      CONVERTED TO ABSOLUTE CROSS-SECTIONS USING THE PREFERRED TOTAL.


      LFORMA ,XLCUTA, PL2A AND PL3A ARE DERIVED BY FITTING SIGMA(N,L)
      USING THE A-D-A-S ENTRY PROGRAMME FOR CHARGE EXCHANGE DATA
      FOR PRINCIPAL QUANTUM SHELL N=3 AT ALL TABULATED ENERGIES

   L-SPLITTING IS RECONSTITUTED FROM THE JET N-SHELL RESOLUTION DATA 
   BLOCK USING  ITS L-SHELL FORM PARAMETERS.  THE DATA SET THUS EXACTLY
   MATCHES THE JET DATA SET IN APPLICATION.  NOTE THE L-SHELL FORM
   PARAMETERS ARE OPTIMIMISED AROUND THE N-SHELLS RESPONSIBLE FOR 
   VISIBLE LINE CHARGE EXCHANGE SPECTROSCOPY EMISSION.
