Measurements of 1 GeV proton total scattering cross section on H, He, $^6$Li, C, O and Pb targets

Igo, G.J. ; Friedes, J.L. ; Palevsky, H. ; et al.
Nucl.Phys.B 3 (1967) 181-187, 1967.
Inspire Record 1389662 DOI 10.17182/hepdata.33327

Total cross sections have been measured for H, He, 6 Li, C, O and Pb targets for 1 GeV incident energy protons. From the differential elastic scattering data published elsewhere, we also obtain the total elastic scattering and reaction cross sections for H, He, C and O. When our data are combined with other measurements in the same energy region, it is found that the total and reaction cross sections can be fit by the formulae σ T = 47 A 0.82 and σ R = 42 A 0.67 mb. It is also observed that the total and reaction cross sections for negative pions on nuclei can also be fit with these same A -dependencies.

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.

MEASUREMENT OF DELTA SIGMA-l AND C (L, L) = (L, L : 0, 0) N PROTON PROTON SCATTERING BETWEEN 300-MEV AND 800-MEV

Auer, I.P. ; Ditzler, W.R. ; Hill, D. ; et al.
Phys.Rev.D 29 (1984) 2435-2468, 1984.
Inspire Record 205458 DOI 10.17182/hepdata.23728

Measurements are reported of the difference ΔσL between proton-proton total cross sections for parallel and antiparallel spin states and of the parameter CLL for proton-proton elastic scattering near 90°, for thirteen energies between 300 and 800 MeV. The ΔσL results agree well with previous ANL ZGS and SIN data, but disagree with recent results from TRIUMF. Attempts to understand the cause of the discrepancy have been unsuccessful, but possible sources are discussed. The ΔσL and CLL results have been used with other experimental data to extract quantities which depend only on spin-singlet, coupled spin-triplet, and spin-triplet partial waves. Structure is found in these quantities, which appears to be associated with the resonantlike D21 and F33 partial waves. Additional similar structure is also found, which may be due either to the P03 partial wave or the (P23,F23) partial-wave pair.

MEASUREMENT OF THE DIFFERENCE IN P P TOTAL CROSS-SECTIONS FOR PURE PARALLEL AND ANTIPARALLEL TRANSVERSE SPIN STATES (DELTA SIGMA (T AT T(P) = 487-MEV, 639-MEV, AND 791-MEV

The difference between total cross sections in pure transverse-initial-spin states for the p−p interaction has been measured at Tp=487, 639, and 791 MeV, using a frozen-spin target. A comparison with previous data and available phase-shift analyses is made.

Measurement of the $p p$ Cross-sections in the Momentum Range 0.9-2.0 GeV/c

Shimizu, F. ; Kubota, Y. ; Koiso, H. ; et al.
Nucl.Phys.A 386 (1982) 571-588, 1982.
Inspire Record 11839 DOI 10.17182/hepdata.37042

The pp total, elastic, and all the inelastic cross sections were measured at 11 momenta in the range 0.9–2.0 GeV/c. No clear structure was observed in their momentum dependences. The momentum dependence of the total cross section agrees quite well with the result of a phase-shift analysis by Arndt. Our measurement of the ppπ 0 and pnπ + cross sections served to normalize the earlier systematic but relative and extrapolated measurements of these cross sections over a narrower momentum range. Calculations by König and Kroll based on a pion exchange model including the effect of an I = 1 dibaryon did not fit the single-pion production cross sections.

Measurement of $\Delta - \sigma_L$ in Proton Proton Scattering Between 300-{MeV} and 800-{MeV}

Phys.Rev.D 24 (1981) 2008, 1981.
Inspire Record 10751 DOI 10.17182/hepdata.51322

We have measured the difference between proton-proton total cross sections for parallel and antiparallel longitudinal spin states [ΔσL=σtot(⇄)−σtot(⇄)] at 13 incident energies between 300 and 800 MeV, which cover the region of possible D21 and F33 diproton resonances. The present experiment has strongly confirmed the structure previously observed at the Argonne Zero Gradient Synchrotron. No additional narrow structure has been found.

Measurements of the Total Cross-Section Difference and the Parameter C(LL) in p p Scattering with Longitudinally Polarized Beam and Target

Auer, I.P. ; Beretvas, A. ; Colton, E. ; et al.
Phys.Lett.B 70 (1977) 475-478, 1977.
Inspire Record 5342 DOI 10.17182/hepdata.27516

We have measured the difference between the pp total cross-sections for parallel and anti-parallel longitudinal spin states at beam momenta of 3 and 6 GeV/ c . These results, combined with our previous measurements, at lower momenta, are useful in clarifying a striking structure appearing at around 1.5 GeV/ c . We have also measured for the first time, the spin-spin correlation parameter C LL ( t ) in pp elastic scattering at 6 GeV/ c . We observe evidence for an exchange with A 1 -like quantum-numbers.
