Megjegyzések:	The ^7Li(p,n)^7Be reaction is widely used as neutron source for neutron induced reaction cross section measurements, and for ^7Be radioactive source production. There are two prominent structures in the excitation function, a narrow resonance between E_p = 2.2 - 2.3 MeV, and a broad peak, around E_p = 5 MeV. There are tension between the experimental data sets both in the position and the width of this latter structure, as well as in the absolute scale of the data. In the present work the ^7Li(p,n)^7Be reaction is investigated using the activation technique, with the aim of providing comprehensive cross section data covering the second structure and connecting prior literature data sets. The irradiations were performed with the Atomki cyclotron accelerator with pairs of thin foil targets, thus with precisely controlled reaction energy in the range of E_p = 3.5 - 13 MeV. After the irradiations the activity of the samples was measured using a highpurity germanium detector. The energy uncertainty of the new data points is much smaller than in any of the previous works, while the cross section uncertainty is comparable with the most precise literature data. A consistent data set was obtained connecting the most recent and most precise literature data sets. With the new data the absolute magnitude of the ^7Li(p,n)^7Be reaction cross section is constrained and became more precise.
