  Source:  The data consists of results of CTMC calculations made at the University of Missouri over 
              the period 1997-98.
     
  Comments:  The usual alpha parameters for high n-shell extrapolation were decided as a preferred curve 
             through alphas deduced from adjacent n-shell cross-section pairs.  For the helium receiver
             case, a convincing preferred curve was obtained with alpha always greater than 2.5. For
             the carbon receiver case, there was a much larger data scatter and the preferred curve
             dipped as low as 1.1.  This was considered unsound without further investigation.  The total
             cross-section obtained from the CTMC method is in fact a true total including all n-shells
             of the receiver rather than a sum simply over the the explicit partial cross-sections.  We
             chose to recalculate alpha from the difference between the partial cross-section sum to n=9
             from the total.  The alphas as a function of energy in this case show smooth behaviour and
             do not fall below 2.5.  It seems that this comparison provides a rough measure of 
             convergence to asymptotic behaviour at high n of the CTMC calculations.  It is safest to
             adopt the new alpha when it differs significantly from the older definition.  Also
             n-shell extrapolation from the adf01 explicit data should be treated with great caution
             when the two alphas differ.  
 
             The data was assembled as ADAS data files of type adf01 at JET Joint Undertaking in the
             period 29 June -1 July1998.
