Experimental verification of the Kramers-Kronig relation at high energy

Alvensleben, H. ; Becker, U. ; Biggs, P.J. ; et al.
Phys.Rev.Lett. 30 (1973) 328-332, 1973.
Inspire Record 84536 DOI 10.17182/hepdata.21393

The real part of the forward amplitude for Compton scattering on protons was measured through the interference between the Compton and Bethe-Heithler amplitudes by detecting the zero-degree electron pairs asymmetrically. The measurement was made at an average photon energy of 〈k〉=2.2 GeV, and an average momentum transfer to the recoil proton 〈t〉=−0.027 (GeV/c)2. The result confirms the prediction of the Kramers-Kronig relation.

Neutron-proton charge-exchange scattering, 3-12 gev/c

Miller, E.L. ; Elfield, M. ; Reay, N.W. ; et al.
Phys.Rev.Lett. 26 (1971) 984-987, 1971.
Inspire Record 69018 DOI 10.17182/hepdata.37275

We report a high-statistics measurement of the neutron-proton charge-exchange differential cross section for incident momenta 3 to 12 GeVc, and four-momentum transfers 0.003 to 0.85 (GeVc)2. The data are normalized absolutely to ±20%. The differential cross section is characterized by a sharp peak at small momentum transfers, with a gentler exponential behavior at large momentum transfers. This shape is remarkably independent of the incident momentum.

Determination of the photoproduction phase of rho0 mesons

Alvensleben, H. ; Becker, U. ; Chen, M. ; et al.
Nucl.Phys.B 25 (1971) 342-350, 1971.
Inspire Record 68820 DOI 10.17182/hepdata.33835

We have measured large-angle electron-positron pairs from the reaction γ +Be → Be+e + +e − in the e + e − invariant-mass region of 610 < m < 850 MeV/ c 2 . The phase of the photoproduction amplitude of the ϱ-meson at 4.1 – 6.1 GeV was found to deviate from pure imaginary by 11.8° ± 4.4° which corresponds to a ratio of the real to imaginary ϱ-nucleon amplitude of β = −0.2 ± 0.1.

Measurement of p+p --> pi++d at 90-degrees and 5 GeVc

Ruddick, K. ; Ratner, L.G. ; Edwards, K.W. ; et al.
Phys.Rev. 165 (1968) 1442-1445, 1968.
Inspire Record 944945 DOI 10.17182/hepdata.26528

The differential cross section for the process p+p→π++d was measured at 5.0 GeVc for a center-of-mass angle of 90°. The experiment was done on the Argonne ZGS with the same apparatus as was used in a recent 90° proton-proton elastic scattering experiment. The extracted proton beam of the ZGS was made to impinge upon a CH2 target. The pion and deuteron were detected by two spectrometers, each containing magnets and a scintillation-counter telescope, in coincidence. The incident beam flux was measured by a radiochemical analysis of the CH2 target. The 90° cross section at 5.0 GeVc was found to be 35±9 nb/sr.
