Description
Photoabsorption on two-nucleon systems γ{NN}→NN, and the
inverse reaction, hard bremsstrahlung NN→{NN}γ, are widely used
to test different theoretical ideas of the nucleon-nucleon interaction.
The reaction pp→{pp}s γ, where diproton {pp}s is a proton pair in
1S0 state, has been observed with the ANKE spectometer at COSY-
Jülich. It is kinematicaly very similar to well-studied reaction pn→dγ,
however dynamically they significantly differ from each other due to
the different quantum numbers of diproton and deuteron. As a result
multipole contributions will also be significantly different. In this talk we will present the progress on obtaining the analyzing power Ay of the pp→{pp}sγ reaction at forward angles at several energies in the
region of ∆(1232) isobar exictation: 500, 550 and 700 MeV. Together with its differential cross section measured earlier, this will help to
better estimate the multipole contributions to this reaction.
