Diproton, analyzing power, hard bremsstrahlungAbstract
The reaction γ + {pp}s → p + p, where diproton {pp}s is a proton pair in 1S0 state, is a spin-isospin partner of the fundamental reaction of deuteron photodisintegration. The inverse reaction, the hard bremsstrahlung p + p → γ + {pp}s, has been observed with the ANKE spectometer at COSY-Jülich. In addition to differential cross section measured earlier, in this work it's analyzing power has been measured at forward angles at several energies in the region of Δ(1232) isobar exictation.
