Function adas.xxdtes

Attempts to determine whether a configuration string is in standard or Eissner form.

Parameters

config : str

configuration string in Eissner or ADAS standard form.

Returns

is_eissner : bool

True if config is in Eissner format.

is_standard : bool

True if config is in standard format.

is_bundle : bool

True if config is in bundle format (a '*' is found).

is_parent : bool

True if config is in parent format (a '[…]' is found).

info : dict

extra information about the configuration

'cfg_top' : leading part of config. string in Eissner
            format (no leading blank, trailing blanks)
'cfg_tail': trailing part of config. string in Eissner
            format (no leading blank, trailing blanks)
'nvlce'   : outer electron n-shell if recognisable
             -1 otherwise
'lvlce'   : outer electron l-shell if recognisable
             -1 otherwise

Notes

The maximum length of the configuration string is 98 characters.

Not pure python - calls a fortran shared object.

References

Eissner notation is a compact representation of the configuration and the appendix in the documentation of adas701 gives details: http://www.adas.ac.uk/man/chap7-01.pdf
