 due to symmetry it is sufficient to merely consider the migration into the bc
 configuration.
 an activation energy of 1.2 eV is obtained.
+actually another barrier exists to reach a 100 type configuration.
 
 in path two, the carbon atom moves towards the same silicon atom, however,
 it escapes the 110 plane and forms a 0-10 oriented db.
