Measurement of the $\bar{p} p \to \bar{n} n$ Cross-section at Low $\bar{p}$ Momenta

Bruckner, W. ; Dobbeling, H. ; Guttner, F. ; et al.
Phys.Lett.B 169 (1986) 302-308, 1986.
Inspire Record 219986 DOI 10.17182/hepdata.30264

First measurements of the differential cross section are presented for p ̄ p → n ̄ n at LEAR in the momentum range between 180 and 600 MeV/ c . The differential cross sections show a forward peaking followed by a smooth drop-off. No indication of the “bump-dip” structure reported at higher momenta has been observed. The angle-integrated charge-exchange cross sections are determined down to E n ̄ n cm = 6.6 MeV .

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.
