Abstract
The \(^{6}\)Li(p,\(\gamma \))\(^{7}\)Be reaction is of interest in many different astrophysical scenarios, as for example the early stages of the star evolution. Recently a resonant structure was observed at E\(_{cm}\) = 195 keV but it is still not confirmed by both theoretical and experimental studies. In order to investigate the existence of the resonance and to constrain the \(^{6}\)Li(p,\(\gamma \))\(^{7}\)Be S-factor at low energies a direct measurement was performed at LUNA. A High Purity Germanium was used in close geometry. A Silicon detector was inserted in backward geometry in order to detect the \(\alpha \) particles by \(^{6}\)Li(p,\(\alpha \))\(^{3}\)He reaction. Five solid targets were irradiated from E\(_p\) = 80 keV up to E\(_p\) = 390 keV and the ongoing analysis suggests there are no resonances.
