The P(p) S reaction is one of the few remaining reactions whose rate uncertainty has a strong impact on classical novae model predictions. To reduce the nuclear uncertainties associated to this reaction, we measured the P(He,t) S reaction at the ALTO facility. Simultaneous detection of the triton and proton decays from the populated resonances will provide the proton branching ratios. The astrophysical context of this work, the current situation of the P(p) S reaction rate, the experimental set-up and the analysis of the single and coincidence events will be presented.

Abstract
The P(p) S reaction is one of the few remaining reactions whose rate uncertainty has a strong impact on classical novae model predictions. To reduce the nuclear uncertainties associated to this reaction, we measured the P(He,t) S reaction at the ALTO facility. Simultaneous detection of the triton and proton decays from the populated resonances will provide the proton branching ratios. The astrophysical context of this work, the current situation of the P(p) S reaction rate, the experimental set-up and the analysis of the single and coincidence events will be presented.File in questo prodotto:
