Hello Guix!
Attached is a patch to add the SPARTA Direct Simulation Monte Carlo
Software.
There maybe is a problem with the source URL: The URL always points to
the latest version of the source tar ball which is constantly updated
and immediately released by upstream. This means that the hash of the
source tar ball available at this URL changes several times a month. Is
this acceptable or does anyone have an idea how this should be handled?
Thank you!

+through a hierarchical Cartesian grid that overlays the simulation
+box. The grid is used to group particles by grid cell for purposes of
+performing collisions and chemistry. Physical objects with
+triangulated surfaces can be embedded in the grid, creating cut and
+split grid cells. The grid is also used to efficiently find
+particle/surface collisions.")
