Elastic differential cross sections were measured at 6 energies between 2.3 and 6 BeVc for π++p and π−+p. The behavior of the secondary peak as a function of energy and charge is shown. Evidence for considerable resonance structure is seen in the angular distributions.

Inspire Record 1389621 DOI 10.17182/hepdata.29776

The elastic scattering of 3.55 GeV/ c π + and π − mesons by protons was measured at centre-of-mass angles between 165° and 177°. The angular distributions for 864 events show a steeply rising backward peak for π + p, while the shape is less clear for π − p.

The π + p cross section for elastic scattering from hydrogen was measured at seven incident energies ranging from 20.8 to 95.9 MeV for an angular range from 60° to 145°. The experimental set-up is discussed in detail as well as the method used for data analysis. A table of results and a set of phase shifts are provided.

Low-energy proton proton scattering near the interference minimum using a windowless gas jet target

Dombrowski, H. ; Khoukaz, A. ; Santo, R. ;
Nucl.Phys.A 619 (1997) 97-118, 1997.
Inspire Record 459312 DOI 10.17182/hepdata.36348

In the energy region around 380 keV (lab.) and at detection angles near 45° (lab.) the cross section of proton-proton scattering exhibits a deep minimum, since the Coulomb amplitude and the nuclear amplitude almost cancel each other out, resulting in a pronounced deviation from pure Mott scattering. A new set of precise data in the-energy range between 300 and 407 keV was recorded using the accelerator of the IKP Münster by employing a thin gas jet target with an areal density smaller than 8 × 10 14 cm −2 . For the first time p-p scattering near the interference minimum was studied under single scattering conditions using a high quality ion beam (energy spread <40 eV). Since the energy smearing was two orders of magnitude lower than that of the former measurements, a more detailed evaluation of the data was feasible, resulting in differential cross sections near the minimum which are smaller than published before. The measured values cannot be explained by the interference of the Coulomb and the nuclear amplitude alone but suggest the need for vacuum polarization or other additional effects. The position of the minimum was determined to be (382.8 ± 0.1) keV.

K-minus-p interactions from 594 to 820 mev/c

Bertanza, L. ; Bigi, A. ; Carrara, R. ; et al.
Phys.Rev. 177 (1969) 2036-2047, 1969.
Inspire Record 55654 DOI 10.17182/hepdata.70773

K−−p interactions in the Columbia-BNL 30-in. hydrogen bubble chamber were studied at nine momenta from 594 to 820 MeVc. The results for elastic-scattering and zero-prong-plus-V0 events are presented here. Differential cross sections are given for the K−p, K¯0n, and Λπ0 final states. A fit to the K¯N channels was obtained which shows the effects of a 32− resonance at 1701 MeV. This energy is appreciably displaced from the peak in the inelastic cross section.

Discontinuous behaviour in large angle proton-proton elastic scattering at high energies

Allaby, J.V. ; Cocconi, G. ; Diddens, A.N. ; et al.
Phys.Lett.B 25 (1967) 156-159, 1967.
Inspire Record 1389227 DOI 10.17182/hepdata.754

Measurements of elastic proton-proton differential cross sections for angles between 65° and 90° c.m.s. have been made at 8, 9, 10, 11, 14, 15 and 21 GeV/c. The shape of the angular distribution is found to change suddenly between 8 and 11 GeV/c. An interpretation of this discontinuous behaviour in terms of the reactive effects of baryon-antibaryon pair production is proposed.

Pi- p forward elastic scattering near 1 gev/c

Nucl.Phys.B 46 (1972) 630-636, 1972.
Inspire Record 74955 DOI 10.17182/hepdata.8020

We have measured the differential cross section of the reaction π − p→ π − p in the range 0.92 ⩽ cos θ c.m. ⩽ 0.99 at 15 momenta between 0.875 and 1.580 GeV/ c . The results we report complete the available data; previous measurements of this reaction do not extend beyond cos θ c.m. =0.90. We compare our experimental results with dispersion relation predictions. A comparison of our results for B , the slope of the differential cross section, with earlier results shows many discrepancies.

Pi+ p elastic scattering between 0.6 and 0.8 gev/c

Bowler, M.G. ; Cashmore, R.J. ; Kaddoura, A. ;
Nucl.Phys.B 37 (1972) 133-160, 1972.
Inspire Record 75335 DOI 10.17182/hepdata.8085

In this paper we present the π + p differential elastic scattering cross sections at five momenta between 0.6 and 0.8 GeV/ c . The data were collected in a bubble chamber exposure and consequently are susceptible to different systematic errors from counter experiments. Our results are generally in good agreement with those of counter experiments in the same momentum range and with the predictions of the various elastic partial wave analyses. The majority of partial wave analyses do not however yield parameters which fit our data in detail without modification.
