<p>where Rc is the cutoff. As explained above, an interaction involving
one or two body sub-particles may be computed even for r > Rc.</p>
<p>For style <em>body</em>, the following coefficients must be defined for each
pair of atoms types via the <aclass="reference internal"href="pair_coeff.html"><spanclass="doc">pair_coeff</span></a> command as in
the examples above, or in the data file or restart files read by the
<aclass="reference internal"href="read_data.html"><spanclass="doc">read_data</span></a> or <aclass="reference internal"href="read_restart.html"><spanclass="doc">read_restart</span></a>
commands:</p>
<ulclass="simple">
<li>epsilon (energy units)</li>
<li>sigma (distance units)</li>
<li>cutoff (distance units)</li>
</ul>
<p>The last coefficient is optional. If not specified, the global cutoff
