Abstract
The non-relativistic quantum mechanical description of meta-stable states which arise by perturbation of embedded eigenvalues is considered. The model given by the Hamiltonian
is studied for small λ. If −Δ+v has a positive eigenvalue then when λ=0,H has an embedded eigenvalue. The corresponding eigenstate, Φ, is a meta-stable state for λє0. The time evolution of Φ underH,e −itH Φ is estimated uniformly int.
