Low energy $\Lambda p \to \Lambda p$ cross section measurement and determination of S-wave scattering lengths

Alexander, G. ; Benary, O. ; Karshon, U. ; et al.
Phys.Lett. 19 (1966) 715-719, 1966.
Inspire Record 1389622 DOI 10.17182/hepdata.30161

The Λ p å Λ p cross section has been measured in the Λ-momentum range of 120 to 320 MeV/ c using 238 events. A comparison with the effective range approximation yielded the values a s = −2.46, a t = −2.07, r s = 3.87 and r t = 4.50 in fm.

$K^- p$ total and elastic cross sections at 2.66 GeV/c

Ficenec, J.R. ; Trower, W.P. ;
Phys.Lett.B 25 (1967) 369-372, 1967.
Inspire Record 1389627 DOI 10.17182/hepdata.29435

At an incident kaon momentum of 2.66 GeV/ c we have measured the total and elastic cross sections to be 30.2 and 5.70 mb respectively. The elastic scattering angular distribution is dominated by a single diffraction peak; and when this peak is fit to an exponential in momentum transfer t , the first order term is both necessary and sufficient. This fit evaluated at t =0 is consistent with a purely imaginary forward scattering amplitude. Our data when compared with that of others indicates no shrinkage of the diffraction peak. The entire angular distribution was also fit to a Legendre series, with order 9 being required to represent the data.

Forward scattering of GeV photons from carbon and tungsten

Eisenhandler, E. ; Mistry, N. ; Mostek, P. ; et al.
Phys.Lett.B 24 (1967) 347-348, 1967.
Inspire Record 1389656 DOI 10.17182/hepdata.29584

Small angle (≈3°) scattering of GeV photons from carbon and tungsten has been measured. The results are compared with the predictions of a simple “optical theorem” model, where the total cross-section for photon absorption is taken to be the incoherent sum of absorption on single nucleons.
