We have analyzed 2560 events in the final-state K O 1 K O 1 n produced in π − p interactions at 5, 7 and 12 GeV/ c . We observe the S ∗ (1070), f O and A 2 decaying into K O 1 K O 1 . Resonance parameters, cross sections, and branching ratios are given.

Inspire Record 51286 DOI 10.17182/hepdata.21770

Cross sections for the reaction γ+p→π0+p for incident gamma-ray energies of 2.0 to 5.0 GeV and for baryon four-momentum transfers squared of 0.5 to 4.0 (GeV/c)2 are presented. The results are compared with theoretical predictions based on Reggeized vector-meson exchange.

Polarization Parameter in p-p Scattering from 1.7 to 6.1 BeV

Grannis, P. ; Arens, J. ; Betz, F. ; et al.
Phys.Rev. 148 (1966) 1297-1302, 1966.
Inspire Record 50914 DOI 10.17182/hepdata.26642

The polarization parameter in proton-proton scattering has been measured at incident proton kinetic energies of 1.7, 2.85, 3.5, 4.0, 5.05, and 6.15 BeV and for four-momentum transfer squared between 0.1 and 1.0 (BeV/c)2. The experiment was done with an unpolarized proton beam from the Bevatron striking a polarized proton target. Both final-state protons were detected in coincidence and the asymmetry in counting rate for target protons polarized parallel and antiparallel to the scattering normal was measured. The maximum polarization was observed to decrease from 0.4 at 1.7 BeV to 0.2 at 6.1 BeV. The maximum of the polarization at all energies studied occurs at a four-momentum transfer squared of 0.3 to 0.4 (BeV/c)2.

Deuteron Electromagnetic Form Factors for F-3-2 < q2 < F-6-2

Benaksas, D. ; Drickey, D. ; Frerejacque, D. ;
Phys.Rev. 148 (1966) 1327-1331, 1966.
Inspire Record 944953 DOI 10.17182/hepdata.26653

Two groups of measurements have been made on the elastic scattering of electrons by deuterium; in each case we observed the recoil deuteron instead of the scattered electron. In the first case the spectrometer was set at 45° so that magnetic scattering was unimportant (about 10%) and we deduced the electric form factors of the deuteron. In the second case deuterons were observed at 0°, allowing us to measure directly the magnetic form factor of the deuteron. Form factors of the neutron were deduced from these measurements for the transfer values q2=3, 4, and 5 (F−2). Preliminary results were given in a first paper. Here we also include a description of the experimental setup and discuss relativistic and exchange-current corrections.

pi++p Interactions at 646 MeV

Oliver, John D. ; Nadelhaft, I. ; Yodh, G.B. ;

A 14-in. liquid-hydrogen-filled bubble chamber in a 17.5-kG magnetic field was exposed to a beam of negative pions produced by the Cosmotron at Brookhaven National Laboratory. About 26 000 pictures were taken and examined for the following final states: (1) elastic scattering (π−p); (2) π+ production (π−π+n); (3) π0 production (π−π0p); (4) neutrals. Values for the cross sections for these processes are σ(elastic)=17.56±0.43 mb, σ(π+)=7.14±0.23 mb, σ(π0)=4.65±0.17 mb. The elastic-scattering angular dependence in the c.m. system is fitted by a power-series expansion in cosθ and gives the following coefficients: a0=0.27±0.02, a1=1.48±0.11, a2=3.86±0.22, a3=−0.29±0.53, a4=−0.65±0.28, a5=1.69±0.52 (units: mb/sr). Cross sections for multiple-pion production were also measured: σ(π−π+π0n)=0.33±0.04 mb, σ(π−π+π−p)=0.08±0.02 mb. The total neutral cross section was σ(neutrals)=11.78±0.43 mb; the total charged events cross section was σ(charged)=29.76±0.69 mb; and the total cross section was σ(total)=41.54±0.82 mb. For single-pion production events, two-body mass distributions and angular distributions were compared with the predictions of the Olsson-Yodh isobar model.

Elastic Electron-Deuteron Scattering

Grossetete, B. ; Drickey, D. ; Lehmann, P. ;
Phys.Rev. 141 (1966) 1425-1434, 1966.
Inspire Record 944959 DOI 10.17182/hepdata.26656

We present results on elastic electron-deuteron experiments performed at Orsay. The range of momentum transfers is 0.6 to 2 F−2. Two kinds of measurements have been taken detecting the scattered electron: one with a solid CD2 target, the other with a liquid target. The data are analyzed with the nonrelativistic theory, which gives slightly positive neutron form factors and a magnetic neutron form factor nearly equal to the magnetic proton form factor.
