#### Abstract

Analyzing-power measurements A$\sbsp{n}{coinc}$, A$\sbsp{s}{coinc}$, and A$\sbsp{l}{coinc}$ are presented for the reaction $\sp{12}$C($\vec p ,p\sp\prime\gamma$)$\sp{12}$C$\sp{\*}$ (15.11 MeV). A polarized proton beam at 318 MeV was used and data were taken for 3 mutually perpendicular directions of polarization. A scintillator hodoscope was used for scattered proton detection and 4 BGO detectors for the 15.11 MeV $\gamma$-ray. Data are presented for 8 azimuthal directions of the scattered proton around the beam direction, and for the polar angles averaged between 3.3$\sp\circ$ and 11.2$\sp\circ$. The data are compared with non-relativistic calculations (DW81) and relativistic calculations with explicit treatment of exchange (DREX). The average size of the asymmetries measured is comparable to these predictions but does not agree closely with either prediction.
