The (14)C(n,gamma)(15)C reaction plays an important role in inhomogeneous big bang models. In Timofeyuk et al. [Phys. Rev. Lett. 96, 162501 (2006)] it was shown that the (14)C(n,gamma)(15)C radiative capture at astrophysically relevant energies is a peripheral reaction, i.e., the overall normalization of its cross section is determined by the asymptotic normalization coefficient (ANC) for (15)C -> (14)C + n. Here we present new measurements of the (14)C(d,p)(15)C differential cross sections at deuteron incident energy of 17.06 MeV and the analysis to determine the ANCs for neutron removal from the ground and first excited states of (15)C. The results are compared with previous estimations.
