International audience; Spectroscopy of an unbound nucleus $^{17}$C was performed using the SAMURAI spectrometer at RIBF of RIKEN. Six resonances were observed for the $^{16}$C+n system with relative energies of 0.52, 0.77, 1.36, 1.91, 2.22 and 3.20 MeV. The excitation energies ($E_x$) of the observed resonances were deduced, by taking into account the states of the $^{16}$C fragments identified by coincident $\gamma $ rays, as $E_x$=(3.02), 1.51, (3.86), 2.65, (4.72) and 3.94 MeV. The orbital angular momenta of the two observed states in $^{17}$C at $E_x$=2.65 and 3.94 MeV were determined as 1 by comparing parallel momentum distributions with theoretical predictions.
