Abstract: Channeling of accelerated protons technique was used for determination of carbon atoms location in Ni crystal lattice. ¹³C isotope was dissolved in Ni samples. At angular scan near crystal axis <110> and plane (100) γ-rays yield of resonance reaction ¹³С(р, γ)¹⁴N and backscattered on Ni nuclei protons was measured. It was shown that at concentration level 0.18 at. % carbon atoms located in octahedral voids, and at concentration level 0.46 at. % carbon atoms located in tetrahedral voids of nickel.
