| Popis: | The 3 H(d , γ )5 He reaction has been measured using a 500-keV pulsed deuteron beam incident on a stopping titanium tritide target at Ohio University’s Edwards Accelerator Laboratory. The time-of-flight (TOF) technique has been used to distinguish the γ -rays from neutrons detected in the bismuth germinate (BGO) γ -ray detector. A stilbene scintillator and an NE-213 scintillator have been used to detect the neutrons from the 3 H(d , n )4 He reaction using both the pulse-shape discrimination and TOF techniques. A newly-designed target holder with a silicon surface barrier detector to simultaneously measure α -particles to normalize the neutron count was incorporated for subsequent measurements. The γ -rays have been measured at laboratory angles of 0°, 45°, 90°, and 135°. Information about the γ -ray energy distribution for the unbound ground state and first excited state of 5 He can be obtained experimentally by comparing the BGO data to Monte Carlo simulations. The 3 H(d , γ )/3 H(d , n ) branching ratio has also been determined. |
