  As an extension of previous work, we calculate the production cross-section
of heavy neutron-rich isotopes by employing the quantal diffusion description
to ${}^{48} \text{Ca} + {}^{238} \text{U}$ collisions. The quantal diffusion is
deduced from stochastic mean-field approach, and transport properties are
determined in terms of time-dependent single-particle wave functions of the
time-dependent Hartree-Fock (TDHF) theory. As a result, the approach allows for
prediction of production cross-sections without any adjustable parameters. The
secondary cross-sections by particle emission are calculated with the help of
the statistical GEMINI++ code.
