ABSTRACT.  We consider a spinless particle coupled to a photon field 
and prove that even if the Schr\"odinger operator $p^2 + V$ does not 
have eigenvalues the system can have a ground state. We describe the coupling by means of the 
Pauli-Fierz Hamiltonian and our 
result holds in the case where the coupling constant $\al$ is small.
