The 22Mg(α,p)25Al reaction was mesured with a 5MeV/u 22Mg beam in order to measure the cross section over a wide centre-of-mass energy range to disentangle the existing discrepancies among the existing statistical calculations. The experiment was recently performed using the Active Target Time Projection Chamber (ATTPC) that overcomes the difficulties imposed by the solid targets when using low intensity beams.
The ATTPC was filled with He gas with enough pressure to stop the incoming 22Mg with a two-fold purpose: maximize the efficiency of the detector close to 100% while measuring the whole excitation function within the region of interest for the 22Mg(α,p)25Al reaction. Experimental data for this direct measurement will play a key role in network calculations. Preliminary results will be presented
