We have studied the reaction e−+p→e−+π++n by detecting the final electron and pion in coincidence. Data are presented in the region of virtual photon mass squared from -0.18 to -1.2 GeV2, and virtual photoproduction center-of-mass energy and angle from 1.85 to 2.50 GeV and 0 to 20°, respectively.

MEASUREMENT OF THE TOTAL CROSS-SECTION DIFFERENCE DELTA (SIGMA-L) (P P IN THE ENERGY RANGE FROM 0.52-GEV TO 2.8-GEV

Bystricky, J. ; Chaumette, P. ; Deregel, J. ; et al.

The total cross section difference Δα L (pp) for proton-proton scattering with beam and target polarized longitudinally parallel and antiparallel, respectively, has been measured using the polarized proton beam from SATURNE II and a frozen spin polarized proton target. The beam polarization was reversed from pulse to pulse, and at each energy Δα L was measured for both signs of target polarization. The data below 800 MeV confirm the previously observed structures. The cross section difference is found to change by 8.0 ± 0.5 mb between 520 MeV and 760 MeV. At the higher energies the results show no indication for similar structures or for a change of the sign of Δα L .

Measurement of the spin correlation parameter A00kk for pp elastic scattering in the energy range 0.72–1.1 GeV

Bystricky, J. ; Chaumette, P. ; Deregel, J. ; et al.
Nucl.Phys.B 258 (1985) 90623 483-504, 1985.
Inspire Record 221352 DOI 10.17182/hepdata.33761

The spin correlation parameter A00kk (pp) has been measured in the angular region 45°<θCM<90° at 0.719, 0.834, 0.874, 0.934, 0.995 and 1.095 GeV using the SATURNE II polarized proton beam incident on a polarized target. The parameters A00nn(pp and A00sk(pp) were measured at 0.874 in the same angular region.

Measurement of the Total Cross-section Difference $\Delta \sigma^-$t ($p p$) in the Energy Range From 0.43-{GeV} to 2.4-{GeV}

Perrot, F. ; Azaiez, H. ; Ball, J. ; et al.
Nucl.Phys.B 278 (1986) 881-904, 1986.
Inspire Record 228310 DOI 10.17182/hepdata.33569

The SATURNE II polarized proton beam and the Saclay frozen spin polarized proton target were used to measure the total cross section difference Δσ T = −2 σ 1 tot at 26 energies between 0.43 and 2.4 GeV. Here Δσ T is the total cross section difference for transverse beam and target spins parallel and antiparallel, respectively, and σ 1tot is one of spin-dependent terms in the total cross section σ tot . The energy dependence of Δσ T below 1 GeV shows similar structures as for Δσ L . An additional minimum appears at about 1.3 GeV, which involves a structure in singlet spin partial waves.
