Abstract
The 2V sector of the Lee model with boson sources at zero separation is considered from the Tamm- Dancoff point of view. This involves three singular integral equations which are solved by appealing to results previously gained in the Lehmann-Symanzik-Zimmermann method of solution. Two scattering amplitudes and a production amplitude are rederived via the state vectors and an equation for the determination of the two-meson exchange potential is discussed.
