Indirect Study of the H-2(d,p)H-3 and H-2(d,n)He-3 Reactions at Astrophysical Energies via the Trojan Horse Method

The H-2(d,p)H-3 and H-2(d,n)He-3 reactions have been indirectly studied by means of the Trojan Horse Method applied to the quasi-free H-2(He-3, p(3)H)H-1 H-2(He-3, n(3)He)H-1 reaction at 18 MeV of beam energy. This is the first experiment where the spectator (here H-1) has been detected in coincidence with the charged participant, avoiding the limitations of standard neutron detectors. The d - d relative energy has been measured from 1.5 MeV down to 2 keV, at center of mass angles from 40A degrees to 170A degrees. Indirect angular distributions are compared with the direct behaviour in the overlapping regions. RI Aliotta, Marialuisa /H-2567-2012
