Baker, W.F. ; Berkelman, Karl ; Carlson, P.J. ; et al.
Phys.Lett.B 28 (1968) 68902621 291-295, 1968.
Inspire Record 56828 DOI 10.17182/hepdata.29075

The angular distributions of K<sup loc="post">+</sup>p and π<sup loc="post">+</sup>p backward elastic scattering have been measured at 5.2 and 6.9 GeV/c. Backward π<sup loc="post">-</sup>p and K<sup loc="post">-</sup>p elastic scattering were studied at 6.9 GeV/c. Backward peaks are observed in K<sup loc="post">+</sup>p scattering with an energy dependence of the form s<sup loc="post">−4</sup>.

Total neutron-nuclei cross-sections at 10 {GeV/c}

Engler, J. ; Horn, K. ; Konig, J. ; et al.
Phys.Lett.B 28 (1968) 64-66, 1968.
Inspire Record 928257 DOI 10.17182/hepdata.29173

Total neutron cross-sections were determined for He, Li, Be, C, Al, Fe, Cu and Pb at an average neutron momentum of 10 GeV/ c . The results agree very well with total proton-neuclei cross-sections at 20 GeV/ c . The interaction radii inferred from the cross-sections are in remarkable agreement with the half-density radii as obtained from electron scattering.

On $K_L$ - $K_S$ Regeneration in Copper

Bohm, A. ; Darriulat, P. ; Grosso, C. ; et al.
Phys.Lett.B 27 (1968) 594-598, 1968.
Inspire Record 1374884 DOI 10.17182/hepdata.69210

The transmission regeneration amplitude after a thick copper block has been measured. The quantity {∣ƒ(0)- overlineƒ(0)∣ }/{k} varies from 20.0 $\pm$ 1.4 mb at 2.75 GeV/c to 13.6 $\pm$ 1.2 mb at 7.25 GeV/c. Results are in agreement with optical model calculations in which real and imaginary parts of the amplitudes for single nucleon scattering are determined from forward dispersion relations and total cross-sections.

AN INVESTIGATION OF THE 1.4-GeV/c**2 NUCLEON ISOBAR IN PROTON PROTON INTERACTIONS

Tan, T.H. ; Perl, Martin L. ; Martin, F. ; et al.
Phys.Lett.B 28 (1968) 195-198, 1968.
Inspire Record 52678 DOI 10.17182/hepdata.29198

The production of N ∗ (1400) isobar in the reaction pp → pN ∗+ (1400), where N ∗ (1400) → n π + and p π 0 , is investigated with the aid of one-pion exchange model. The one-pion exchange mechanism does not seem to dominate the production process. The isospin of N ∗ (1400) is found to be I = 1 2 , and the elasticity of the resonance is estimated to be 0.66.

Phys.Rev.Lett. 18 (1967) 571-574, 1967.
Inspire Record 52312 DOI 10.17182/hepdata.21767

The reaction γ+p→π++n has been investigated for photon energies between 1.2 and 3 GeV and pion c.m. angles from 2.5 to 15°. The cross section is strongly peaked in the forward direction and shows resonance structure in the region of the N32*(1920) and N12*(2190).

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.
