Function adas.xxdata_49

Reads universal charge exchange data from an adf49 file and returns all of its contents in a dictionary.

Parameters

file : str

full name of ADAS adf49 file

Returns

fulldata : dict

contents of the adf49 file

    'file'       :  adf49 filename
    'symbd'      :  donor ion element symbol  string
    'izd'        :  donor charge
    'indd'       :  donor state index
    'nenrgy'     :  number of energies
    'n'          :  array of scaled n shells
    'alpha'      :  alpha parameter
    'beta'       :  beta parameter
    'gamma'      :  array of gamma parameter for scaling n shells
    'delta'      :  array of delta parameter for scaling x sects
    'ltype'      :  1/0 indicating whether l-shell parameters
                    are present in file
    'lparms'     :  type of L parms used (currently only 1)
    'enrgya'     :  array of scaled energies
    'sigta'      :  array of scaled total cross sectio
    'signa'      :  array of scaled n-shell cross sections

Notes

Example

Read in the scaled universal data for CX capture from n=2 of hydrogen and print the first 5 scaled total cross sections and the set of scale n.

>>> import adas as adas
