Polarization measurement of the anti-p p ---> anti-n n charge exchange at 8 gev/c

Le Du, P. ; Guisan, O. ; Beusch, W. ; et al.
Phys.Lett.B 44 (1973) 390-392, 1973.
Inspire Record 84827 DOI 10.17182/hepdata.28100

The p p → n n polarization has been measured at 8 GeV/ c and for − t values ranging from 0 up to 0.8 (GeV/ c ) 2 . A small and negative polarization has been found.

The charge exchange anti-p p ---> anti-n n at 5.0 and 7.76 gev/c near the forward direction

Lee, J.G. ; Harckham, A. ; Letheren, M. ; et al.
Nucl.Phys.B 52 (1973) 292-300, 1973.
Inspire Record 84235 DOI 10.17182/hepdata.32683

The differential cross section for the charge exchange p p → n n has been measured with high statistics at 7.76 GeV/ c and at 5.0 GeV/ c . The 7.76 GeV/ c data show a very narrow [ Δt ⪅ 0.01 (GeV/ c ) 2 ] forward peak superposed on a slow exponential fall-off.

Anti-p p elastic and charge exchange scattering at 230 mev

Kohno, H. ; Kaneko, S. ; Murata, Y. ; et al.
Nucl.Phys.B 41 (1972) 485-492, 1972.
Inspire Record 75157 DOI 10.17182/hepdata.6879

Reactions p p → p p and p p → n n were studied at the kinetic energy 230 MeV of incident p by using bubble chamber films. Total cross sections for both of the reactions were found to be 51.2 ± 1.6 mb and 9.1 ± 0.6 mb, respectively. Differential cross sections are well explained by the phenomenological theory given by Bryan and Phillips.
