Abstract We establish existence of an infinite family of exponentially-decaying non-radial C 2 solutions to the equation Δu +ƒ( u )=0 on R 2 for a large class of nonlinearities ƒ. These solutions have the form u ( r , θ)= e im θ w ( r ), where r and θ are polar coordinates, m is an integer, and w : [0, ∞)→ R is exponentially decreasing far from the origin. We prove there is a solution with each prescribed number of nodes.
