 TITLE=/ Medium energy gamma rays following radiative capture of 50
         MeV polarized protons on 11B /;
 PURPOSE=/ This report aims at presenting the analyzing power
           measurement of medium energy gamma rays following radiative
           caputure of 50 MeV polarized protons and at showing the
           dependence of the analyzing power on the spin direction of
           the captured proton. /;
