  We use the parton and hadron cascade (PACIAE) model and the dynamically
constrained phase-space coalescence (DCPC) model to investigate the productions
of (anti)hypertriton and light (anti)nuclei generated by 0-10% centrality
$^{12}$C+$^{12}$C, $^{24}$Mg+$^{24}$Mg, $^{40}$Ca+$^{40}$Ca, and
$^{64}$Cu+$^{64}$Cu collisions at $\sqrt{S_{NN}}$ = 200 GeV with $|y|$ $<$ 1.5
and $p_{T}$ $<$ 5. We study the yield ratios of the antiparticle to particle
and the rapidity distributions of the different (anti)nuclei. We find that the
amounts of antimatter produced are significantly lower than that of the
corresponding particles, the results of theoretical models are well consistent
with the PHOBOS data. The yield ratios of the particle to antiparticle in
different transverse momentum regions are also given, and we find that the
ratios are raise with the increase of the transverse momentum.
