Abstract
We study decay properties of solutions ϕ of the Schrödinger equation (−Δ+V)ϕ=Eϕ. Typical of our results is one which shows that ifV=o(|x|−1/2) at infinity or ifV is a homogeneousN-body potential (for example atomic or molecular), then ifE<0 and\(\alpha > \sqrt { - E} ,e^{\alpha \left| x \right|} \psi \notin L^2 \left( {\mathbb{R}^n } \right)\). We also construct examples to show that previous essential spectrum-dependent upper bounds can be far from optimal if ϕ is not the ground state.
