From scattering to very deeply bound neutrons in 208Pb

Two new methods are developed which improve and extend the iterative moment approach to the extrapolation of the nuclear mean field from positive towards negative energy and to the prediction of various single-particle properties. These two methods still use as sole input a set of phenomenological optical-model potentials. They are improvements of the original approach because they yield more accurate predictions. They are extensions of the original approach because they provide the imaginary part of the mean field, in addition to its real part; this enables one to evaluate scattering cross sections, spectral functions and occupation probabilities, which was not possible in the previous version.
