For any rank 2 of simple Lie algebra, the relativistic Chern-Simons system has the following form:

* where is the Cartan matrix of rank . There are three Cartan matrix of rank 2: , and . A long-standing open problem for this equation is the question of the existence of non-topological solutions. In this paper, we consider the and case. We prove the existence of non-topological solutions under the condition that either or and . We solve this problem by a perturbation from the corresponding and Toda system with one singular source.
