Time-dependent Hartree-Fock (TDHF) theory has achieved a remarkable
success in describing and understanding nuclear many-body dynamics
from nucleons’ degrees of freedom. We here report our investigation of multinucleon
transfer (MNT) processes employing the TDHF theory. To calculate
transfer probabilities for channels specified by the number of protons and neutrons
included in reaction products, a particle-number projection (PNP) method
has been developed. The PNP method is also used to calculate excitation energies
of reaction products. Combined use of the PNP method with a statistical
model, we can evaluate MNT cross sections taking account of effects of particle
evaporation. Using these methods, we evaluate MNT cross sections for
40,48Ca+124Sn, 40Ca+208Pb, and 58Ni+208Pb reactions. From systematic analyses,
we find that cross sections for channels with a large reaction probability are
in good agreement with experimental data. However, the agreement becomes
less accurate as the number of transferred nucleons increases. Possible directions
to improve the description are discussed.
