| We consider semi-classical Schrödinger operators with matrix-valued, long-range, smooth potential, for which different eigenvalues may cross on a codimension one submanifold. We denote by $h$ the semiclassical parameter and we consider energies above the bottom of the essential spectrum. Under some invariance condition on the matricial structure of the potential near the eigenvalues crossing and some structure condition at infinity, we prove that the boundary values of the resolvent at energy $\lambda$, as bounded operators on suitable weighted spaces, are $O(h^{-1})$ if and only if $\lambda$ is a non-trapping energy for all the Hamilton flows generated by the eigenvalues of the operator's symbol. |
