Proton-Proton Interaction

Physical Review Letters, 1961
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.

The external proton beams and the proton‐proton experiments

AIP Conference Proceedings, 1980
The 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.

Protonated Heme

Chemistry – A European Journal, 2007
AbstractThe ions formally corresponding to protonated heme [FeII–hemeH]+ have been obtained by collision‐induced dissociation from the electrospray ionization of microperoxidase (MP11) and their gas‐phase chemistry has been studied by FTICR mass spectrometry.

QCD in High-Energy Proton-Proton and Proton-Antiproton Collisions

1985
The experimental and theoretical investigation of nucleon-nucleon collisions at high energies allows to explore the structure of the nucleon by large momentum transfer (deep-inelastic) processes. In these lectures the structure of the nucleon from momentum scales Q > 1 GeV/c (

When Is a Proton Not a Proton?

Chemistry - A European Journal, 1998
In 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 ...

Protons and how they are transported by proton pumps

Pflügers Archiv - European Journal of Physiology, 2008
The 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, 1992
The {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

Experiments with 315-Mev Polarized Protons: Proton-Proton and Proton-Neutron Scattering

Physical Review, 1957
The 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.

Proton-Proton Collisions

2016
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.
