Purpose

Parameters

items

For calculate: list of projectiles (nuclide symbols), enclosed in apostrophes '.
For read: list of external files, might include wildcards.

targets

For calculate only: list of target nuclei (nuclide symbols), enclosed in apostrophes '.

iactions

For calculate only: list of interactions, enclosed in apostrophes '. Currently only the default, nf, is supported.

calculate

Calculates cross sections.

model()

For calculate only: selects cross section model. Currently only the default is supported.

energy(lo,hi)

For calculate only: selects energy range (MeV/u) to be calculated.

ne()

For calculate only: selects number of energy table breakpoints.

eps()

For calculate only. Not yet implemented

write

Writes the calculated cross sections into as many files as there are target nuclei.
File naming conventions:

<prefix><targ>nf.xs

where <targ> are the nuclide symbols of the target nuclei.
(prefix)

export(fmt)

Exports the calculated tables in some non-native format, at present only <fmt>="gd" is implemented to export for the gd plot program. File naming convention is:

<prefix><targ>nf.xs.gd

where <targ> are the nuclide symbols of the target nuclei.
(prefix)

prefix()

Output path for the calculated tables. It is just a prefix put in front of the file naming convention. Might be a directory or just part of a file name.

read

Reads external cross sections from files specified in the item list.

read

Not yet implemented.

delete

Deletes cross section tables. In the current release filtering is not implemented, so everything is deleted.

debug

Debug switch. Lots of output!

Remark

Examples

• xs '1H,2H,3H,3He,4He,7Li,9Be,10B,11B,10C,11C,12C' '1H,16O' /calc ne(200) e(0,500)
  

  calculates nuclear fragmentation cross sections for the listed projectiles and target nuclei 1H,16O (which combine to water). Table range is from 0 to 500 MeV/u.

• xs * * * / write pref(/tmp/)
  

  writes cross sections to files named /tmp/1H.nf.xs and /tmp/16O.nf.xs, respectively, for the example above.

• xs * * * / delete
  

  deletes all cross sections.
