Experimental and theoretical study of deuteron-proton elastic scattering for proton kinetic energies between $T_p=882.2\text{MeV}$ and $T_p=918.3\text{MeV}$

Abstract

New precise unpolarised differential cross sections of deuteron-proton elastic scattering have been measured at 16 different deuteron beam momenta between $p_d=3120.17\text{MeV}/c$ and $p_d=3204.16\text{MeV}/c$ at the COoler SYnchrotron COSY of the Forschungszentrum Jülich. The data, which were taken using the magnetic spectrometer ANKE, cover the equivalent range in proton kinetic energies from $T_p=882.2\text{MeV}$ to $T_p=918.3\text{MeV}$. The experimental results are analysed theoretically using the Glauber diffraction model with accurate nucleon-nucleon input. The theoretical cross section at $T_p=900\text{MeV}$ agrees very well with the experimental one at low momentum transfers $|t|<0.2(\text{GeV}/c{)}^2$.
