One of the most promising ways to make new n-rich heavy nuclei is through the use of multi-nucleon transfer (MNT) reactions. One needs reliable models to predict the outcomes of these reactions due to the difficulties of studying these reactions, which may have cross sections in the pb-nb region. We have made measurements of the yields of MNT products in the interaction of Ec.m. = 450 MeV 136Xe + 208Pb (235 yields), Ec.m. = 619 MeV 204Hg + 198Pt, (46 yields), Ec.m. = 451 MeV 136Xe + 198Pt (329 yields) and Ec.m. = 336 and 692 MeV 204Hg + 208Pb. We have compared these results with other measurements and with the predictions of the semi-classical GRAZING-F, di-nuclear system (DNS) and Intermediate Quantum Molecular Dynamics (ImQMD) models. We find that The GRAZING-F model correctly predicts the magnitudes of the transfer cross
sections for small transfers, but underestimates the cross sections for large transfers. The DNS model underestimates the yields of the PLFs and most TLFs, while the ImQMD model does the best overall job of describing all the yields .We point out further possible tests of these models.
