We present the final results of a measurement of the polarization parameter P 0 in high-energy n~-p and p-p elastic scattering, performed using a target which contained polarized protons. Data were taken at beam momenta of 6.0, 8.0, 10.0 and 12.0 GeV/c for n-, and of 6.0, 10.0 and 12.0 GeV/c for n+ and p, in the interval of invariant four-momentum transfer squared-t from 0.1 to 0.75 (GeV/c)2.

PI+ PI+ correlations. The correlation function is parametrized as follows R = 1 + CONST(NAME=BEC-LAM)*EXP(-CONST(NAME=BEC-R)**2*MQ**2), where MQ**2 = M(pi1 + pi2)**2 - 4*M(pi)**2.
