Abstract
It is proved that the λ(φ4)2 quantum field theory with a space cutoff has asymptotic fields as a strong limit of operators in Fock space. The commutation relations between these asymptotic operators and the total Hamiltonian inform us in part of the spectrum of the total Hamiltonian.Keywords
