CROSS SECTION DATA FORMAT
|
|
In downloaded files, each collision process is defined by a block consisting of
|
|
1st line
|
|
Keyword in capitals indicating the type of the collision. Possible collision types are elastic, effective, excitation,
|
|
ionization, or attachment (capital letters required, key words are case sensitive), where "elastic" is used to denote
|
|
the elastic momentum transfer cross section and where "effective" denotes the total momentum transfer cross section (sum
|
|
of elastic momentum transfer and total inelastic cross sections). The latter is useful for solving the Boltzmann
|
|
equation in the 2-term approximation.
|
|
2nd line
|
|
Name of the target particle species. This name is a character string, freely chosen by the user, e.g. "Ar". Optionally
|
|
for excitation processes, the name of the corresponding excited state can be specified on the same line, separated from
|
|
the first name either by arrow "->" (dash + greater than) or by double-head arrow "<->" (less than + dash +
|
|
greater than), e.g. "Ar -> Ar*" and "Ar <-> Ar*", respectively. In the later case BOLSIG+ will automatically
|
|
define the inverse superelastic process, constructing the superelastic cross-section by detailed balancing, and
|
|
considering the indicated excited state as the target. In this case, the ratio of statistical weights must be input in
|
|
the 3rd line (see below). Alternatively, superelastic collisions could be defined explicitly as excitation collisions
|
|
with a negative electron energy loss with user input cross sections and species name, "Ar*", for example.
|
|
3rd line
|
|
For elastic and effective collisions, the ratio of the electron mass to the target particle mass. For excitation or
|
|
ionization collisions, the electron energy loss (nominally the threshold energy) in eV. For attachment, the 3rd line is
|
|
missing. In case of an excitation process where an excited state has been indicated on the 2nd line using double-head
|
|
arrow "<->", the 3rd line must specify also ratio of the statistical weights of the final state to the initial state
|
|
as the second parameter in 3rd line this is needed by BOLSIG+ to calculate the de-excitation cross-section.
|
|
from 4th line (optionally)
|
|
User comments and reference information, maximum 100 lines. The only constraint on format is that these comment lines
|
|
must not start with a number.
|
|
Finally
|
|
Table of the cross section as a function of energy. The table starts and ends by a line of dashes "------" (at least 5),
|
|
and has otherwise two numbers per line: the energy in eV and the cross section in m2.

These cross sections are the same as those compiled by Phelps with two exception : (1) the rotational excitation
|
|
suggested by Morgan is lower than that of Phelps and (2) We have added the Phelps' data for the 13.86 eV excitation
|
|
process to the Morgan database. Morgan's original data didn't include the 13.86 eV excitation process.
