Deuteron photodisintegration by polarized photons in the region of the $d^{\ast }(2380)$

M. Bashkanov, S. Kay, D. P. Watts +70

We report the first large-acceptance measurement of the beam-spin asymmetry for deuteron photodisintegration ($\vec{\gamma }d\to pn$) in the photon energy range $400<E_{\gamma }<630$~MeV. The mea…
