摘要：

The energy spectra and angular distributions of proton emission in the reaction of Ni-nat(n,xp) at neutron energy 14.6 MeV have been measured by the USTC multitelescope system. The double-differential cross sections of 16 reaction angles from 25 degrees to 164.5 degrees have been obtained in this measurement. The statistical error can be reduced because of the thick target used. The angular distributions show a slightly energy-dependent forward-backward asymmetry. The angle-integrated proton spectrum is compared with ENDF/B-VI evaluation and Grimes' result. The total p-emission cross section is in fair agreement with prediction and evaluation.
