Measurement Of Spin Correlation Parameters Ayy And Axx Of Proton-Proton Scattering At 47.5 Mev

The measurement of the spin correlation parameters of proton-proton scattering at 47.5 MeV has been done by using polarized beam and polarized target. A proton beam which had 50% polarization was provided by p -Ca scattering. The polarized target was a LMN crystal which was maintained 35% polarization by dynamic method during the experiment. The spin correlation parameters A y y and A x x at 90°C CM were measured simultaneously. A y y , A x x and A y y / A x x at 47.5 MeV were -0.287±0.039, -0.713±0.032 and 0.402±0.057, respectively.
