Measurement of the doubly-polarized $\vec{{}^{3}{He}} (\vec{γ}, n) p p$ reaction at 16.5 MeV and its implications for the GDH sum rule

Laskaris, G.; Yan, X.; Mueller, J.; ... - Physics Letters. B

We report new measurements of the double-polarized photodisintegration of 3He at an incident photon energy of 16.5 MeV, carried out at the High Intensity γ-ray Source (HIγS) facility located at Triangle Universities Nuclear Laboratory (TUNL). The spin-dependent double-differential cross sections and the contribution from the three-body channel to the Gerasimov–Drell–Hearn (GDH) integrand were extracted and compared with the state-of-the-art three-body calculations. The calculations, which include the Coulomb interaction and are in good agreement with the results of previous measurements at 12.8 and 14.7 MeV, deviate from the new cross section results at 16.5 MeV. The GDH integrand was found tomore »
