Polarization transfer in the deuteron break-up reaction at 56 MeV

The polarization transfer coefficients K^yy' of the break-up spectra in the reactions ¹²C, ⁵⁸Ni, ²⁰⁹Bi(d, pX) were measured at 56 MeV. In the forwardd angles (13.5° and 20.0°), the K_y^y' data at the break-up peak are nearly equal to 2/3 (the spectator model prediction) and they decrease at both sides of the peak. The deviation due to the deuteron D-state is estimated, using PWBA and DWBA.
