A model for p-p interactions below 350 Mev is studied, which contains a boundary condition to represent the shortrange potential, and a fourth order static perturbative tail for the long-range interaction. The scattering phase shifts and wave functions are found for various energies and quantum states.

Scattering of Protons by Protons
Physical Review, 1953The data of Worthington, McGruer, and Findley (WMF) on scattering of protons by protons show an apparently real contribution to the cross section arising from scattering in the $p$ state. Results of phase shift analysis of these data are presented in Table I and in Fig. 1.

The external proton beams and the proton‐proton experiments
AIP Conference Proceedings, 1980The ZGS was one of the first accelerators in which extracted primary proton beams and experimental halls were part of the initial design. Special features incorporated into the ring made it possible to permanently position extraction magnets, and there was no need to plunge them as in other machines.

Protons and how they are transported by proton pumps
Pflügers Archiv - European Journal of Physiology, 2008The very high mobility of protons in aqueous solutions demands special features of membrane proton transporters to sustain efficient yet regulated proton transport across biological membranes. By the use of the chemical energy of ATP, plasma-membrane-embedded ATPases extrude protons from cells of plants and fungi to generate electrochemical proton ...

Relativistic effects in proton-proton bremsstrahlung
Physical Review C, 1992The {ital pp}{gamma} reaction at intermediate energies is investigated using a modern relativistic meson-exchange potential model. Both the single-scattering and rescattering terms are treated including relativistic corrections. It is shown that for energetic photons in the region near the end-point energy the relativistic spin correction is very large

When Is a Proton Not a Proton?
Chemistry - A European Journal, 1998In spite of the large number of protonated complexes, their use in catalytic cycles has been little explored. The existing examples suggest that catalytic processes initiated by the protonation of a low-valent metal hold promise for the development of selective, efficient, and atom-economical addition reactions under very mild conditions, if the ...

This chapter is intended to give an overview of the basics of the description and simulation of proton-proton (pp) collisions. The terminology is introduced in Sect. 4.1. Section 4.2 contains a brief discussion of parton density functions and Sect. 4.3 introduces the basic concepts for the calculation of hadron–hadron cross sections.

Experiments with 315-Mev Polarized Protons: Proton-Proton and Proton-Neutron Scattering
Physical Review, 1957The polarization in elastic $p\ensuremath{-}p$ and $p\ensuremath{-}n$ scattering at 315 Mev has been measured as a function of the scattering angle. The maximum polarization observed in each of these interactions is approximately 40 percent. A similar measurement of the polarization in $p\ensuremath{-}p$ scattering at 276 Mev is also reported.

Light antinuclei production in proton-proton, proton-nucleus, and antiproton-proton collisions
AIP Conference Proceedings, 2004The experimental data on the antideuteron, antitritium, and antihelium‐3 production in proton‐proton and proton‐nucleus collisions are well reproduced within a simple model based on the diagrammatic approach to the coalescence model. First quantitative estimations of the antideuteron production cross section in antiproton‐proton collisions are ...
