  We extended the Schwinger boson construction to obtain wave functions that
are resonating valence bond (RVB) counterparts of the degenerate coplanar
classical states on the Kagome lattice. We examined all 84 of them on the
36-site cluster and found that they form a narrow energy band. On the 12-site
cluster, there are only four such states and their superpositions accurately
account for the second through fourth exact diagonalization (ED) states, while
the ED ground state is accurately reproduced by allowing a particular two-vison
insertion on top of the q=0 RVB state. Thus, we have established the RVB sign
structures for the low energy states on this cluster.
