  We study the production and decay of the neutral top-pion $\pi_{t}^{0}$
predicted by topcolor-assisted technicolor(TC2) theory. Our results show that,
except the dominant decay modes $b\bar{b}$, $\bar{t}c$ and $gg$, the
$\pi_{t}^{0}$ can also decay into $\gamma\gamma$ and $Z \gamma$ modes. It can
be significantly produced at high energy $e^{+}e^{-}$ collider(LC) experiments
via the processes $e^{+}e^{-}\to \pi_{t}^{0}\gamma$ and $e^{+}e^{-}\to
Z\pi_{t}^{0}$. We further calculate the production cross sections of the
processes $e^{+}e^{-}\to\gamma\pi_{t}^{0}\to\gamma\bar{t}c$ and $e^{+}e^{-}\to
Z\pi_{t}^{0}\to Z\bar{t}c$. We find that the signatures of the neutral top-pion
$\pi_{t}^{0}$ can be detected via these processes.
