Description
An investigation on η’ photoproduction on quasi-free neutron (Deuterium target) is presented, by showing a preliminary estimation of Beam Asimmetry Σ as function of polar angle in the center-of-mass system near the threshold by analyzing the experimental data of GRAAL experiment. The η’ photoproduction channel is useful because it acts as an isospin filter, allowing to select only resonant contributions with one half isospin. The preliminary Σ measurements for the η’ photoproduction off neutron was performed in the energy interval of the interacting γ photon [1447-1475] MeV for four bins in the θ. The present estimations have been compared with the data on the proton channel, published by GRAAL experiment, and they are consistent.
