© The Authors, published by EDP Sciences, 2018. Among reactions with strong impact on classical novae model predictions, 30 P(p,?) 31 S is one of the few remained that are worthy to be measured accurately, because of their rate uncertainty, as like as 18 F(p,?) 15 O and 25 Al(p?) 26 Si. To reduce the nuclear uncertainties associated to this reaction, we performed an experiment at ALTO facility of Orsay using the 31 P( 3 He,t) 31 S reaction to populate 31 S excited states of astrophysical interest and detect in coincidence the protons coming from the decay of the populated states in order to extract the proton branching ratios. After a presentation of the astrophysical context of this work, the current situation of the 30 P(p,?) 31 S reaction rate will be discussed. Then the experiment set-up of this work and the analysis of the single events will be presented.
