  We show that the QCD van der Waals attractive potential is strong enough to
bind a $\phi^{0}$ meson onto a nucleon inside a nucleus to form a bound state.
The direct experimental signature for such an exotic state is proposed in the
case of subthreshold $\phi^{0}$ meson photoproduction from nuclear targets. The
production rate is estimated and such an experiment is found to be feasible at
the Jefferson Laboratory.
