Two-Body Photodisintegration of $^4$He into $t+p$

ORAL

Abstract

The photodisintegration of $^4$He into $t$ and $p$ is being studied using the CEBAF Large Acceptance Spectrometer (CLAS) at the Thomas Jefferson National Accelerator Facility. Real photons produced with the Hall B bremsstrahlung tagging system in the energy range from 0.35 to 1.55 GeV were incident on a cryogenic liquid $^4$He target. Tritons and protons were detected in coincidence in the CLAS which gives a large angular coverage. Kinematic cuts were applied to select the reaction channel of interest, $^4$He$(\gamma,tp)$. Differential cross sections for this process will be presented. These data will constitute the first investigation of $^4$He photodisintegration into $t+p$ for incident photon energies above 0.4 GeV.
