  The $\beta$-delayed neutron decay of $^{17}$B was studied using a radioactive
ion beam. The neutron energies, measured via time-of-flight, give information
on states in $^{17}$C above the $^{16}$C + neutron threshold. States in
$^{17}$C were found at excitation energies of 2.25(2) MeV, 2.64(2) MeV and
3.82(5) MeV, and possibly at 1.18(1) MeV. These low lying states are of
possible interest for nuclear physics as well as for astrophysics.
