The neutron total and capture cross sections of ^natEr were measured at the ANNRI beamline of J-PARC. The neutron capture cross section was determined using Ge and NaI(Tl) spectrometers, while the neutron total cross section was measured with Li-glass detectors. In the present work, the neutron total and capture cross-section results of ^natEr are provided, together with the results of a resonance shape analysis to determine the resonance parameters of low energy resonances of ^166,167Er.
