The Large Hadron Collider forward (LHCf) experiment is designed to verify the hadronic interaction models used in cosmic-ray physics. We measured forward particle spectra with √s = 13 TeV proton-proton collisions at LHC in 2015. In this paper, we report the neutron energy spectra for LHC √s = 13 TeV proton-proton collisions in pseudorapidity η > 10.76 region. We also obtained xF spectra which is made by normalized energy spectra with half of collision energy √s / 2. The spectrum was compared with the one by √s = 7 TeV proton-proton collisions and we confirmed that they are consistent in error size. This result support the existence of collision energy dependence on the forward neutron energy spectra in high energies.
