Nuclear Astrophysics at LNL: the ²⁵Mg(α,n)²⁸Si and ¹⁰B(p,α)⁷Be cases

The National Laboratory of Legnaro (LNL) has a long experience in Nuclear Physics measurements. Recently a new effort to perform Nuclear Astrophysics studies has been initiated. This effort started with the collaboration of LNL with the LUNA (Laboratory for Underground Nuclear Astrophysics) collaboration for the study of targets. After that in 2012, thank to a fruitful collaboration between nuclear astrophysicist and nuclear physics groups involved in neutron detection, the study of the ²⁵Mg(α,n)²⁸Si reaction was developed in order to help solving the ²⁶Al puzzle. For the first time the angular distributions of neutrons emitted by this reaction were studied deeply founding discrepancies between the previous studies in literature. In 2014 the study of ¹⁰B(p,α)⁷Be was performed in order to give a precise normalization to the indirect measurements. This study was done by measuring the activated samples and it is still under analysis. A report of the status of the two experiments will be given in this contribution. (paper)
