Existence and stability of spherically symmetric stationary interfaces in a two-phase boundary problem are studied in RN (N ≥ 2). We show that there exist two such solutions: a large ball and a small one. The linearized eigenvalue problem shows that the large ball is unstable with some fastest growing mode. We specify the mode precisely.
