(Data are provided as scans from the above reference values.)

Processes

  • H0 (n=3 ) + C6+ → H0 (n=2 ) + C6+ + hv (6561Å)
  • H0 (n=3 ) + e → H0 (n=2 ) + e + hv (6561Å)

(Note that included processes are more complex in that full density dependent GCR calculations are used, the above processes are simply an indication of the effective data the ADF22 file provides.)

	NOTE : Working accuracy


	The  working  accuracy  was  obtained  by calculating the population
	structure and hence the effective emission  coefficient  via ADAS310 
	and ADAS311 using three different ion/atom  collision  cross-section  
	databases,i.e. ADF02  type files.An ADF02 type file contains indexed 
	entries  of key ion/atom reaction cross-sections  with  H  and other 
	species. The  first  detailed assessment of ion/atom  cross  section  
	data  for  beam  stopping  was  completed  at  JET  in  1989 ( small
	corrections and  extensions  were made to the file up to 1993). This 
	file was  originally  saved  /adas/adf02/ionatom/h.dat but was later 
	reformatted   and  saved  as  /adf02/sia#h/sia#h_rfm#h.dat.Guided by  
	experimental observations at JET  and the  lack of high quality CCAO 
	calculations  when  the  JET  1989  data set was compiled,the cross-
	sections of the  JET  1989  data  set was considered to be some what 
	under-estimated.A  new  review  of  all  ion/atom collision data was 
	carried  out.  The only substantial contribution  found  was that of
	the  close  coupled atomic  orbital (CCAO) calculations of Toshima &
	Tawara [1].This data together with the data of Janev & Smith [2] was 
	used  to  create  yet  another  ADF02  type  file,sia#h_tosh#h.dat.
	However, the  CCAO  calculations of Toshima & Tawara[1] only include 
	states up to n=4 and so some over-estimation is present,particularly 
	for ion  impact ionisation from n=3 and n=4 shell.The cross-sections 
	contained in this  data set are considered to be  over-estimated.  A 
 	comparative  data  set   was  constructed   which  was  a compromise 
	between both data sets,this is what is  called  the  JET 1997 review 
	data set ,  sia#h_j97#h.dat.  The  JET  1997  review  data  is the 
	preferred  data  set. The  working accuracy  was  obtained  
	by running ADAS310 using  each data set.The  results from using  the
	JET 1997 review data is taken as the most accurate value.The results
	from using the JET 1989  data set are used to obtain a lower  limit.
	The results from the Toshima & Tawara data set are used to obtain an 
	upper  limit. Using  the  values of  the   lower  and  upper limit a 
	percentage difference is used to describe the MAXIMUM deviation from 
	the results obtained using the JET 1997 review data.
