Summary: The spectrum of free Schrödinger operators at the half space with boundary condition \(\phi_ n-Q\phi =0\) \((\phi_ n\) being the normal derivative, Q a selfadjoint operator at the boundary) is investigated and a connection between its negative part and the spectrum of a family of Klein-Gordon type operators is stated.
