Abstract：Let G be a simple undirected graph， with vertex set V＝. The Randic＇ matrix of G is the matrix R＝， where rij＝1/ if the vertices vi and vj are adjacent and rij＝0 otherwise. The Randic＇ energy RE is the sum of absolute values of the eigenvalues of R. The corona of G1°G2 is obtained by connecting each vertex of G1 to all vertices of a copy of G2. In this paper， the Randic＇ energy of corona graphs Ir and Kn°Km are studied.
