 TITLE=/MEASUREMENT OF POLARIZATION IN ELASTIC PP SCATTERING AT
        2.1GEV/C IN THE REGION OF SMALL MOMENTUM TRANSFERS/;
 PURPOSE=/IT IS OF INTEREST TO MEASURE THE POLARIZATION FOR SMALL 'T'
          BECAUSE THE BEHAVIOR OF THE POLARIZATION IN THIS REGION GIVES
          SPECIFIC INFORMATION ON THE AMPLITUDES OF THE SCATTERING
          MATRIX. THE COULOMB SCATTERING REGION IS ESPECIALLY
          INTERESTING BECAUSE THAT IS WHERE THE POLARIZATION CAN BE
          EXPECTED TO BEHAVE IRREGULARY BECAUSE OF INTERFENCE BETWEEN
          THE ELECTROMAGNETIC AMPLITUDES AND THE STRONG-INTERACTION
          AMPLITUDES./;

 COMMENT = FOR ABS(T) [< 0.5 (GEV/C)**2 THE T-DEPENDENCE OF THE POLAR-
     IZATION IS APPROXIMATED BY THE EMPIRICAL FORMULA: P(T)=C*SQRT(ABS
     (T))*EXP(-D*ABS(T)), WITH C=1.3388+-0.106 AND D=2.512+-0.136 (GEV
     /C)**(-2).
     IT IS EASY TO SEE THAT THE POSITION OF THE POLARIZATION MAXIMUM
     T(MAX)=D/2 PRACTICALLY DOES NOT CHANGE IN THE RANGE OF MOMENTA 2
     TO 6 GEV/C.
