Abstract Angular resolved field emission spectra from Nb tips have been investigated around the 〈111〉 orientation in detail. We have observed humps and a low-energy tail in the spectra, depending on the crystal orientation. Their intensities have shown a three-fold symmetry around the 〈111〉 orientation.
