We consider a two channel model of the form He=[Hop00E0]+e[0W12W210] on H=Hop⊕C. The operator Hop is assumed to have the properties of a Schrodinger operator in odd dimensions, with a threshold at zero. As the energy parameter E0 is tuned past the threshold, we consider the survival probability |⟨Ψ0,e−itHeΨ0⟩|2, where Ψ0 is the eigenfunction corresponding to eigenvalue E0 for e=0. We find nonexponential decay laws for e small and E0 close to zero provided that the resolvent of Hop is not at least Lipschitz continuous at the threshold zero.
