Studies of $\bar{p} p \to \bar{n} n$ and $\bar{n} p$ Annihilation at Incident Momenta of 700-{MeV}/$c$ and 760-{MeV}/$c$

The Bombay-Chandigarh-Jammu-Tokyo collaboration Banerjee, S. ; Ganguli, S.N. ; Gurtu, A. ; et al.
Z.Phys.C 28 (1985) 163, 1985.
Inspire Record 217418 DOI 10.17182/hepdata.1974

Results are presented on the charge exchange reaction\(\bar pp \to \bar nn\) and\(\bar np\) annihilations from bubble chamber exposures to antiproton beam of momenta 700 and 760 MeV/c. The differential cross section of\(\bar pp \to \bar nn\) shows a forward spike followed by a clear dip bump structure. Total annihilation cross section of\(\bar np\) for average\(\bar n\) momentum of 700 MeV/c has been evaluated to be 55.4±2.2 mb. The multiplicity, Feynmanx andpT2 distributions for inclusive charged pions in\(\bar pp\) and\(\bar np\) annihilations are found to be similar. The emission of charged pions from\(\bar np\) annihilations are found to be consistent with thermodynamic models with temperature ∼110 MeV.

rivet Analysis
Total Cross-Section for Hadronic Production by e+ e- Annihilation in the Total Center-Of-Mass Energy Range 1.42-GeV - 3.09-GeV

Bacci, C. ; Baldini Celio, R. ; Battistoni, G. ; et al.
Phys.Lett.B 86 (1979) 234-238, 1979.
Inspire Record 141722 DOI 10.17182/hepdata.27311

We report experimental results on the cross section for the reaction e + e − → hadrons as a function of the total c.m. energy in the range W = 1.42–3.09 GeV. The results, combined with those already existing below the charm threshold, clearly indicate a structure for R ( W ) = α ( e + e − → hadrons)/ α ( e + e − → μ + μ − ) in that energy region.

Recoil-proton polarization in neutral-pion photoproduction between 1000 and 1800 mev

Tanaka, N. ; Castro, M.M. ; Milburn, Richard H. ; et al.
Phys.Rev.D 8 (1973) 1-8, 1973.
Inspire Record 81985 DOI 10.17182/hepdata.22112

Measurements are presented of the recoil-proton polarization for π0 photoproduction angles near 64° in the c.m. system. The steep angular dependence observed by others at lower energies persists to at least 1500 MeV, and the polarization crosses through zero near 63° over the entire 900-1600-MeV energy interval. Summary fits are made to available recoil-proton polarization data, 950-1250 MeV, and are found to require terms of order cos3θ, but no higher.
