First measurement of the spin rotation parameter Q for p-/sup 40/Ca elastic scattering at 500 MeV

Journal Article · · Phys. Rev. Lett.; (United States)
The spin rotation parameter Q has been measured for p-/sup 40/Ca-elastic scattering at 497 MeV for 0.01< or =-t< or =0.15 (GeV/c)/sup 2/ with use of the new High Resolution Spectrometer focal plane polarimeter. In conjunction with analyzing power and differential cross section, this measurement uniquely determines the elastic scattering amplitudes up to an arbitrary phase. A parameter-free analysis within the Glauber diffractive approximation with use of N-N phase-shift solutions is presented.
