			<P><B>Description:</B>
			</P>
			<P>Set the dielectric constant for Coulombic interactions (pairwise and
			long-range) to this value. The constant is unitless, since it is used
			to reduce the strength of the interactions. The value is used in the
			denominator of the formulas for Coulombic interactions - e.g. a value
			of 4.0 reduces the Coulombic interactions to 25% of their default
			strength. See the <A HREF = "pair_style.html">pair_style</A> command for more
			details.
