  Within the framework of the dinuclear system model, the influence of mass
asymmetry and the isospin effect on the production of exotic actinides have
been investigated systematically. The isotopic yields populate in multinucleon
transfer reactions of Ca(48), Kr(86), Xe(136), and U(238) bombarding on Cm(248)
are analyzed and compared to the available experimental data. Systematics on
the production of unknown actinides from Ac to Lr via the available stable
elements on the earth (from Ar to U) as projectiles-induced reactions with
$^{232}$Th, $^{238}$U and $^{248}$Cm are investigated thoroughly. Potential
energy surface and total kinetic energy distribution for the reaction system
are calculated and can be used to predict the production cross-section trends.
It is found that the heavier projectile leads to the wider isotopic chain
distribution for the same target. The heavier target-based reactions prefer to
produce plenty of exotic actinides through both mechanisms of deep-inelastic
and quasi-fission reactions. Isospin relaxation plays a crucial role in the
colliding process, resulting in actinide isotopic distribution tends to shift
to the drip lines. Massive new actinides have been predicted at the level of
nanobarn to millibarn. The optimal projectile-target combinations and beam
energies were proposed for the forthcoming experiments.
