In this paper a general connection between the scattering from a bound and a free nucleus is derived in terms of formal scattering theory. The basic idea is to eliminate the interaction Hamiltonian between neutron and nucleus. Then theT-operator for a bound nucleus can be expressed by that of the free nucleus and its binding potential. From this equation an expansion is given as a power series in the binding potential for the nucleus. For slow neutron scattering the first term of the series… Expand
