Factorization property of the deuteron

Using a simple field-theoretic model we show that, in the zero binding limit, the relativistic deuteron wave function has a cluster decomposition; i.e., factors into two separate nucleon wave functions convoluted with a body wave function. The framework of the calculation is a Fock state expansion at equal time on the light-cone. Assuming a quark interchange mechanism, we then derive the deuteron reduced form factor at large momentum transfer, while recovering the standard impulse approximation form at small momentum transfer.
