  Inspired by the progress of the experimental search of the $N\Omega$ dibaryon
by the STAR collaboration, we study $N\bar{\Omega}$ systems in the framework of
quark delocalization color screening model. Our results show that the
attraction between $N$ and $\bar{\Omega}$ is a little bit larger than that
between $N$ and $\Omega$, which indicates that it is more possible for the
$N\bar{\Omega}$ than the $N\Omega$ system to form bound states. The dynamic
calculations state that both the $J^{P}=1^{+}$ and $2^{+}$ $N\bar{\Omega}$
systems are bound states. The binding energy of these two states are deeper
than that of $N\Omega$ systems with $J^{P}=2^{+}$, and the $N\Omega$ system
with $J^{P}=1^{+}$ is unbound. The calculation of the low-energy scattering
phase shifts, scattering length and the effective range also supports the
existence of the $N\bar{\Omega}$ bound states with $J^{P}=1^{+}$ and $2^{+}$.
So the $N\bar{\Omega}$ states are better hexaquark states and stronger signals
are expected in experiments.
