Study of the quasi-free He-3 + Be-9 -> 3 alpha reaction for the Trojan Horse Method

Popis výsledku v původním jazyce

A new study of the quasi-free contribution to the 3He+9Be -> 3 alpha reaction (Q value = 19.004 MeV) at low E3He energy is presented. The reaction was studied in a kinematically complete experiment at beam energy of 4 MeV. To clarify the presence of the quasi-free mechanism, the 4He-5He momentum distribution of the 9Be ground state was extracted. Standard tests were also carried out to confirm the presence of the quasi-free contribution and are reported in this work. The full width at half maximum of the 4He-5He inter-cluster momentum distribution inside 9Be was measured with improved accuracy, by adopting several different approaches that all led to consistent results. These preliminary investigations on the reaction mechanism are fundamental for future studies employing the Trojan Horse Method, with the 5He unbound nucleus as a virtual projectile.
