Indirect measurement of the He-3(n,p)H-3 reaction cross section at Big Bang energies

Popis výsledku v původním jazyce

Nuclear reactions play a key role in the framework of the Big Bang Nucleosynthesis. Anetwork of 12 principal reactions has been identified as themain path that drove the elemental nucleosynthesis in the first 20 min of the history of theUniverse. Among them an important role is played by neutron-induced reactions, which, from an experimental point of view, are usually a difficult task to be measured directly. Nevertheless big efforts in the last decades have led to a better understanding of their role in the primordial nucleosynthesis network. In this work we apply the Trojan Horse Method to extract the cross section at astrophysical energies for the He-3(n,p)H-3 reaction after a detailed study of the H-2(He-3,pt)H three-body process. Data extracted from the present measurement are compared with other published sets.
