The ~2H(d,p)~3H Reaction At Astrophysical Energies Studied Via The Trojan Horse Method And Pole Approximation Validity Test

摘要

In order to understand primordial and stellar nucleosynthesis, we have studied ~2H(d,p) ~3H reaction at 0,4 MeV down to astrophysical energies. Knowledge of this S-factor is interesting also to plan reactions for fusion reactors to produce energy. ~2H(d,p)~3H has been studied through the Trojan Horse Method applied to the three-body reaction ~2H(~3He,pt)H, at a beam energy of 17 MeV. Once protons and tritons are detected in coincidence and the quasi-free events are selected, the obtained S-factor has been compared with direct reactions results. Such data are in agreement with the direct ones, and a pole invariance test has been obtained comparing the present result with another ~2H(d,p)~3H THM one, performed with a different spectator particle (see fig. 1).
