You addition appears to be in the LJ interaction section (don't remember
what it is called), which involves LJ parameters to use between *pairs* of
atom types. In addition to this, there is an [atomtypes] section which
lists all atom types *per se*, giving their 'base' LJ parameters as well
as mass (and some others?). Check the manual chapter on topologies, and on
file formats.
