Initial Research of np Scattering with Polarized Deuterium Target at ANKE/COSY — •Boxing Gou for the ANKE collaboration — Institut für Kernphysik, Forschungszentrum Jülich, 52425 Jülich, Germany — Institute of Modern Physics, Chinese Academy of Sciences, 73000 Lanzhou, China
With the goal of understanding the nuclear forces, the ANKE collaboration has been working on a systematic NN spin program for many years. Due to the lack of free neutron sources experimental data of np scattering are very rare, especially at higher energies. It has been shown that using phase shift analysis (PSA) it is possible to reconstruct np scattering amplitudes from the spin observables of pd→ {pp}1S0n charge-exchange reaction. So far experiments were conducted using polarized deuteron beams and hydrogen target, which led to valuable results. To extend the research up to the highest nucleon energy available at COSY (2.8 GeV), proton beam and polarized deuterium target will be used. This talk will present the results of the commissioning experiment of a deuterium target at ANKE with emphasis on the initial research of charge-exchange reaction.
