The N-14(p,gamma) O-15 reaction has been investigated by the LUNA experiment at the National Laboratory of Gran Sasso (LNGS). This study has been performed with two different technical set-ups. The first one, suitable for the detection of gamma-rays coming from the single transitions, has been realized with a HPGe detector and a solid target. The second has been made of a BGO summing crystal as a detector and a windowless gas target. The high-detection efficiency and the target purity of the gas target set-up allowed to measure the total S-factor down to E-c.m. = 71 keV.

Abstract
The N-14(p,gamma) O-15 reaction has been investigated by the LUNA experiment at the National Laboratory of Gran Sasso (LNGS). This study has been performed with two different technical set-ups. The first one, suitable for the detection of gamma-rays coming from the single transitions, has been realized with a HPGe detector and a solid target. The second has been made of a BGO summing crystal as a detector and a windowless gas target. The high-detection efficiency and the target purity of the gas target set-up allowed to measure the total S-factor down to E-c.m. = 71 keV.
