Multinucleon transfer (MNT) reactions involving heavy projectile and target combinations stand as a promising method for synthesizing yet unknown neutron-rich isotopes and neutron-rich superheavy elements, which may not be possible using hot or cold fusion, fission, or fragmentation reactions. In this thesis, MNT mechanisms in low-energy heavy-ion reactions are investigated within the framework of a quantal diffusion approach based on the stochastic mean-field (SMF) theory. The SMF approach provides a microscopic approach beyond time-dependent Hartree-Fock theory that includes mean-field fluctuations. The quantal transport coefficients, the charge, and mass dispersions of the fragments are calculated to analyze the primary and secondary fragment distributions in MNT reactions, and the results are compared with the experimental data. The observed agreement between the experimental data and SMF results highlights the effectiveness of the quantal diffusion mechanism based on the SMF approach, which does not include any adjustable parameters other than standard parameters of Skyrme energy density functional.
