Description

Coincidence analyzing-power measurements or asymmetries Axcoinc, Aycoinc, and Azcoinc are presented for the 12C(rvec p,p'γ)12C* (15.11 MeV) reaction. A polarized proton beam at 318 MeV was used and data were obtained for three mutually perpendicular directions of polarization. A scintillator hodoscope was used for detecting scattered protons and four BGO detectors for the 15.11-MeV γ rays. Data are presented for eight azimuthal directions of the scattered protons around the beam direction, and for the polar angles averaged between 3.3 degree and 11.2 degree. The data are compared with both nonrelativistic and relativistic calculations. The average size of the asymmetries measured is somewhat less than both predictions and the results do not agree clearly with either prediction
