Symmetric hadron pair production cross section (π+ π+, π+K+, π+p,K+p, andpp) were measured in the range 0.48≦P⊥≦2.29 GeV/c from Be, Cu, and Pb targets bombarded by 70 GeV protons. TheA-dependence exponent as a function ofP⊥ differs for varios pairs.A steep drop of α for meson pairs atP⊥>1.5 GeV/c is observed.

Analyzing powers have been measured for the quasi-elastic ( p → , 2p ) scattering in carbon and copper using a KEK 3.5 GeV polarized proton beam. The present result shows relatively larger analyzing powers compared with the ones obtained for carbon in the energy region 0.52–2.8 GeV at Saclay (Saturne). The t -dependence for C and Cu ( p → , 2p ) is compared with a calculation based on the relativistic impulse approximation and is reproduced well.
