             IAEA A+M Data Unit ALADDIN Dictionary File
             ------------------------------------------

      Data Dictionary of Hierarchical Labels for Atomic and
                    Molecular Collision Processes
      ------------------------------------------------------

HELP ?

To query the ALADDIN dictionary for a label, type the label followed by
a question mark. A description of the contents of this dictionary file
can be viewed by entering DICT followed by a question mark.

For a summary of ALADDIN interactive commands use the command "H"

DICT ?
 This dictionary defines the atomic and molecular collision processes of
relevance to fusion. The dictionary contains the IAEA hierarchical label
for each process along with a symbolic representation of the process.
This symbolic notation conforms to the labelling convention to be
followed. If not included the charge state of any heavy particle must be
included in the ALADDIN entry. When the reaction is uniquely specified
by the process label and the reactants, the indication of the complete
or parts of the final reaction state maybe omitted. (For further details
see the labelling conventions and examples in the users mannual).
 The symbols A, B, and C may stand for any atomic particle ( electron,
ion, atom, molecule, molecular ion), if not explicitly indicated
otherwise.
 All processes which have a numeric suffix relate to multiple electron
processes. The general description of the process can be displayed by
replacing the numeric value with a character k. For three body
reactions, which begin with the symbol '3', the process label in an
entry may have an atomic species as the last component of the label. To
query the dictionary, replace this by the general suffix HP.
