Study of the $\bar{p} p \to \bar{n} n$ Reaction in the Momentum Range 480-{MeV}/$c$ to 728-{MeV}/$c$

Tsuboyama, T. ; Kubota, Y. ; Sai, F. ; et al.

The total and differential p¯p charge-exchange cross sections were obtained at seven momenta in the range 480 to 728 MeV/c. The total cross sections are roughly consistent with other data. The momentum dependences of the Legendre coefficients a1a0, a2a0, and a3a0 of the differential cross sections do not agree well with the predictions of the Bryan-Phillips model, unlike the case of elastic scattering.

Study of $\bar{p} p$ Elastic Scattering in the Momentum Range 374-{MeV}/$c$ to 680-{MeV}/$c$

Sakamoto, S. ; Hashimoto, T. ; Sai, F. ; et al.
Nucl.Phys.B 195 (1982) 1-11, 1982.
Inspire Record 10829 DOI 10.17182/hepdata.34175

p p elastic total and differential cross sections were measured at 17 incident momenta in the range 374–680 MeV/ c . No prominent feature was seen in them to clearly indicate the existence of the S-meson. There is, however, a small enhancement at the S-meson mass, which is equivalent to the elastic total cross section of 4.6 ± 2.1 mb. The behavior of the Legendre expansion coefficients of the angular distributions with incident momentum agrees well the predictions of the OBE model of Bryan and Phillips.

COULOMB - NUCLEAR INTERFERENCE IN PROTON DEUTERIUM ELASTIC SCATTERING AT 600-MEV AND THE REAL PART OF P N SCATTERING AMPLITUDE

Gardes, J. ; Jargeaix, B. ; Lefort, A. ; et al.
Nuovo Cim.A 61 (1981) 121-132, 1981.
Inspire Record 170137 DOI 10.17182/hepdata.37549

The differential cross-sections for the elastic scattering of protons on deuterium have been measured at 600 MeV in the |t| range between 0.003 and 0.030 (GeV/c)2. The results are analysed by using the Bethe and Glauber formalisms taking into account spin effects in deuterium wave function and nucleon-nucleon amplitudes. The ratio between the real and the imaginary parts of the spin-independent protonneutron amplitude αpn deduced from dispersion calculations and phase shift analysis is compared with experimental results.

Data on p p annihilations at rest into K 1 0 K 1 0 ω 0 and K + K − ω 0 are discuss New measurements for the mass, the width and the branching ratio of the ω 0 are presented. Evidence for quasi two-body annihilations p p → ϕπ, p ̄ p → S ∗ π is discussed.
