The Li(p) 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 = 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 Li(p) 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 particles by Li(p) He reaction. Five solid targets were irradiated from E = 80 keV up to E = 390 keV and the ongoing analysis suggests there are no resonances.

Abstract
The Li(p) 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 = 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 Li(p) 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 particles by Li(p) He reaction. Five solid targets were irradiated from E = 80 keV up to E = 390 keV and the ongoing analysis suggests there are no resonances.
