Abstract
The polarization parameter P(t) in pp elastic scattering at 150 GeV/c for momentum transfers 0.2 < −t < 3 GeV;2 has been measured in a t-region where a dip in the cross-section for elastic proton-proton scattering has been observed at the ISR energies. To have a good background rejection, also at high t values with a cross-section of ∿10 nb GeV−2, we needed precise measurements and redundancy in the determination of the kinematics of the reaction. This was achieved with a well collimated beam and by measuring momentum and direction of both outgoing particles in two spectrometers equipped with MWPCs and scintillator hodoscopes (Fig. 1).
