  We study the rational Cherednik algebra attached to the complex reflection
group $G(r,1,2)$. Each irreducible representation $S^\lambda$ of $G(r,1,2)$
corresponds to a standard module $\Delta(\lambda)$ for the rational Cherednik
algebra. We give necessary and sufficient conditions for the existence of
morphism between two of these modules and explicit formulas for them when they
exist.
