Background: Multinucleon transfer (MNT) reactions in actinide systems are a promising method to synthesize transuranium neutron-rich elements. Appropriate theoretical approaches are needed to understand the mechanisms behind MNT. Purpose: We employ a microscopic approach to calculate neutron-rich isotope production in the reaction U238+Cm248 system. Methods: The stochastic mean-field (SMF) approach is used to calculate the primary cross sections in MNT reactions based on the quasifission and inverse quasifission processes, and a statistical de-excitation model with gemini++ code to calculate the secondary fragment cross sections. Results: The calculated cross sections using SMF and GEMINI++ explain available experimental results for the U238+Cm248 system at Ec.m.=898.7 MeV energy. This shows the effectiveness and applicability of the quantal diffusion approach, based on the SMF theory, in heavy-ion collisions. Conclusions: Production of transuranium neutron-rich elements with a proton number up to Z=101 is obtained with sizable cross sections. Theoretical results calculated for the Z=102-105 region, for which there are no experimental data, show that the cross-section values would be lower than the microbarn level. SMF theory does not contain any adjustable parameters other than the standard parameters of the energy density functional used in the TDHF theory and is an important approach for the microscopic understanding of reaction mechanisms.
