Abstract
The ⁴He(γ,pt) reaction has been measured at Eγ = 167 - 209 MeV, using the tagged
bremsstrahlung photon beam of the Saskatchewan Accelerator Laboratory (SAL). Cross
sections were obtained for the four centre-of-mass proton angles 87°, 104°, 120° and 137°.
The experimental apparatus consisted of a liquid helium target and two arms of plastic
scintillator ΔE-E detectors, arranged on opposite sides of the target. Coincident hits in
both detector arms were required to generate a trigger. In order to quantify the low detection
efficiency for tritons, the experiment was simulated by using the GEANT detector simulation
system. The extracted cross sections were compared to previous measurements.
