  The reaction mechanism of deep-inelastic multinucleon transfer processes in
the $^{16}$O+$^{27}$Al reaction at an incident $^{16}$O energy ($E_{\rm
lab}=134$ MeV) substantially above the Coulomb barrier has been studied both
experimentally and theoretically. Elastic-scattering angular distribution,
total kinetic energy loss spectra and angular distributions for various
transfer channels have been measured. The $Q$-value- and angle-integrated
isotope production cross sections have been deduced. To obtain deeper insight
into the underlying reaction mechanism, we have carried out a detailed analysis
based on the time-dependent Hartree-Fock (TDHF) theory. A recently developed
method, TDHF+GEMINI, has been applied to evaluate production cross sections for
secondary products. From a comparison between the experimental and theoretical
cross sections, we find that the theory qualitatively reproduces the
experimental data. Significant effects of secondary light-particle emissions
are demonstrated. Possible interplay between fusion-fission, deep-inelastic,
multinucleon transfer and particle evaporation processes are discussed.
