	<P>The following coefficients must be defined for each pair of atoms
	types via the <A HREF = "pair_coeff.html">pair_coeff</A> command as in the examples
	above, or in the data file or restart files read by the
	<A HREF = "read_data.html">read_data</A> or <A HREF = "read_restart.html">read_restart</A>
	commands:
	</P>
	<UL><LI>D0 (energy units)
	<LI>alpha (1/distance units)
	<LI>r0 (distance units)
	<LI>cutoff (distance units)
	</UL>
	<P>The last coefficient is optional. If not specified, the global morse
	cutoff is used.
	</P>
	<P><B>Restrictions:</B>
	</P>
	<P>The <I>morse</I> potential does not support the
	<A HREF = "pair_modify.hmtl">pair_modify</A> <I>mix</I> option. Coefficients for all i,j
	pairs must be specified explicitly.
