WAS MEASURED AT THE BEAM LINE POLARIMETER 1(BLP1) LOCATED AFTER
THE RING CYCLOTRON. THE BLP1 CONSISTS OF FOUR PAIRS OF
CONJUGATE-ANGLE PLASTIC SCINTILLATORS. P(POLARIZED)+P ELASTIC
SCATTERING WAS USED AS THE ANALYZING REACTION, AND A
SELF-SUPPORTING CH2 TARGET WITH A THICKNESS OF 1.1MG/CM2 WAS USED
AS THE HYDROGEN TARGET. THE ELASTICALLY SCATTERED AND RECOIL
PROTONS WERE DETECTED IN KINEMATICAL COINCIDENCE WITH A PAIR OF
SCINTILLATORS. */
