[en] The radiative proton capture ¹³C(p,γ)¹⁴N and the inverse ¹⁴N(γ,p)¹³C reactions show unusually narrow and strong resonance peaks at E_p=1.7476 MeV and E_γ=9.172 MeV, respectively. In the present work, calculations of the cross sections for the ¹³C(p,γ)¹⁴N and the ¹⁴N(γ,p)¹³C reactions are performed using both the Breit-Wigner single-resonance formula and the radiative direct-capture model. The result calculated using the direct-capture reaction theory implies that the strong resonance peak in the cross section ¹³C(p,γ)¹⁴N at E_p=1.7476 MeV is due to the capture of particles having a d_3/2 wave by the ¹³C core nucleus
