Nuclear Spectroscopy with Two-Nucleon Transfer Reactions

The aspects of two-nucleon transfer reactions that depend on nuclear structure can be isolated in structure amplitudes $G$, which do not depend on the kinematics or scattering states of the reaction. The calculation of these amplitudes from microscopic nuclear models is illustrated in a number of examples. The structure amplitudes measure the parentage and the degree to which a nuclear state possesses the particular correlations predicated by the fact that the pair is transferred to or from a light nuclide which itself has definite and simple correlations among its nucleons. Several specific nuclear reactions are considered in some detail, and the structure amplitudes for many nuclear levels are given.
