[en] The capture reaction ¹⁴N(p,γ)¹⁵O has been investigated in the energy range E_p=0.2 to 3.6 MeV with the use of windowless gas targets as well as implanted ¹⁴N solid targets of high isotopic purity. The measurement of absolute cross sections, γ-ray angular distributions and excitation functions is reported. The data provide information on the capture amplitudes involved in the transitions to all bound states of ¹⁵O. The astrophysical S-factor at stellar energies has been determined by means of theoretical fits. The result of S(0)=3.20 keV . b is in good agreement with the value incorporated in the compilations. Also discussed are the nuclear physics aspects of the data. (orig.)
