Abstract

A complete measurement of the polarization transfer observables has been made for the first time in the (p, p') reaction at Intermediate energies. Measurements are reported for the 12C(p, p1')12C reaction to the 1+, T = 0(12.71 MeV) and l+, T = 1(15.11 MeV) states at 500 MeV at laboratory scattering angles of 3.5°, 5.5°, 7.5°, and 12.0°. Linear combinations of these observables are shown to exhibit a very selective dependence on the isoscalar and isovector spin-dependent components of the nucleon-nucleon interaction. To the extent of the validity of the single collision approximation, these amplitudes are compared directly to the free nucleon-nucleon amplitudes at small momentum transfers (<1 fm−1).

    The strong spin-orbit coupling causes an azimuthal asymmetry from which the polarization perpendicular to the nucleon momentum can be extracted. Polarimetry is often performed after a momentum-analyzing magnetic deflection of the protons in a spectrometer [22–26]. This also automatically provides the spin-precession which enables the measurement of the longitudinal polarization component.
