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.

Pion Production in 650-MeV p-p Collisions

Guzhavin, V.M. ; Kliger, G.K. ; Kolganov, V.Z. ; et al.
Sov.Phys.JETP 19 (1964) 847-854, 1964.
Inspire Record 1387586 DOI 10.17182/hepdata.70070

The angular and energy distributions of pions produced by 650-MeV protons and pion-nucleon correlations were studied using a liquid hydrogen bubble chamber. The present investigation indicates that the experimental angular distributions of neutral and charged pions are consis- tent with the assumption of isotopic spin conservation. The contributions of rrN subsystem states with isospin T 11'N = 7' 2 and % are measured; the contribution of the latter is 72 ± 3%.

A bubble chamber study of proton-proton interactions at 4 GeV/c Part I—Elastic scattering, single-pion and deuteron production

Ooletti, S. ; Kidd, J. ; Mandelli, L. ; et al.
Nuovo Cim.A 49 (1967) 479-498, 1967.
Inspire Record 1185329 DOI 10.17182/hepdata.981

Elastic scattering, single-pion and deuteron production have been investigated. The cross-section for elastic scattering is σelastic = (13.5±0.3) mb. The angular distribution has been fitted to dσ/d|t|=(dσ/d|t|)0 e −bt in the region of low values oft. The best fit givesb=(6.7±0.5) (GeV/c)−2 and (dσ/d|t|)0=(91±5) mb(GeV/c)−2. The cross-sections for ppπ0, pnπ+ reactions are respectively (2.6±0.3) mb and (9.7±0.4) mb. These reactions are dominated by the (3/2, 3/2) nucleonpion isobar production and by forward backward collimation of the nucleons. The production rates for the isobars ++1238 , +1238 , +1500 have been estimated, taking into account the experimental peripheral behaviour of the interaction. In the pnπ+ reaction they are (50±2)%; (10±3)%; (4±3)%. In the ppπ+ reaction the production of ++1238 is estimated to be (45±10)%. The dπ+ and dπ+π+π- reaction cross-sections are respectively (0.03±0.01) mb, and (0.04±0.01) mb.

Passive scalar fluctuations in intermittent turbulence

Crisanti, A. ; Falcioni, M. ; Paladin, G. ; et al.
EPL 14 (1991) 541-546, 1991.
Inspire Record 314520 DOI 10.17182/hepdata.857

We discuss how the spatial intermittency of energy dissipation in 3D fully developed turbulence affects the small-scale statistics of passive scalars. We relate the passive-scalar behaviour to the diffusion properties of particle pairs in turbulent fluids. We thus find the intermittency correction to the -5/3 Obukhov-Corrsin law for the power spectrum of a passive scalar at wavenumber k where molecular diffusion and viscosity play a negligible role (inertial convective subrange). This correction is positive at difference with the negative correction to the -5/3 Kolmogorov law for the energy spectrum. We finally show that the structure functions of passive scalars have scaling exponents linear in the moment order, even in the framework of multifractal models.

Observation of a New Structure in the Difference Between the $p p$ Total Cross-sections for Antiparallel and Parallel Longitudinal Spin States

Auer, I.P. ; Colton, E. ; Halpern, H. ; et al.
Phys.Rev.D 34 (1986) 2581, 1986.
Inspire Record 230143 DOI 10.17182/hepdata.23425

We have measured the difference between the pp total cross sections for parallel and antiparallel longitudinal spin states at beam momenta of 2.75, 2.92, 3.25, and 3.48 GeV/c. These results reveal possible new structure in this momentum range.

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.

TRANSVERSE SPIN DEPENDENCE OF THE P P TOTAL CROSS-SECTION DELTA sigma-t FROM 0.8-GEV/C TO 2.5-GEV/C

Madigan, W.P. ; Bell, D.A. ; Buchanan, J.A. ; et al.
Phys.Rev.D 31 (1985) 966-975, 1985.
Inspire Record 216906 DOI 10.17182/hepdata.23564

The difference ΔσT=σ(↓↑)-σ(↑↑) between the proton-proton total cross sections for protons in pure transverse-spin states, was measured at incident momenta 0.8 to 2.5 GeV/c in experiments performed at the Los Alamos Clinton P. Anderson Meson Physics Facility and the Argonne Zero Gradient Synchrotron. In agreement with other data, peaks were observed at center-of-mass energies of 2.14 and 2.43 GeV/c2, where D21 and G41 dibaryon resonances have been proposed.
