The scattering of protons by protons and the meson field of the proton

Physica, 1948
Abstract New calculations are made on the scattering of protons by protons with several values of the potential energy of the proton, this energy being assumed to be the meson potential. The results of these calculations are compared with the available experimental material.

Proton-proton bremsstrahlung with polarized protons

2008
The asymmetry in proton-proton bremsstrahlung is given for a variety of kinematic conditions in the soft photon approximation. It is argued that the asymmetry may be more sensitive to the unknown higher-order terms than the cross section and is shown that several models giving similar cross sections give quite different asymmetries, which could thus be

Light antinuclei production in proton-proton, proton-nucleus, and antiproton-proton collisions

AIP Conference Proceedings, 2004
The 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 ...

Proton Shuttles in CeO2/CeO2−δ Core–Shell Structure

ACS Energy Letters, 2019
We report a confined proton transportation in the CeO2/CeO2−δ core–shell structure to build up proton shuttles, leading to a super proton conductivity of 0.16 S cm–1 for the electrolyte and advance...

High Proton Conductivity Achieved by Encapsulation of Imidazole Molecules into Proton-Conducting MOF-808.

ACS Applied Materials and Interfaces, 2019
Metal-organic frameworks (MOFs), as newly emerging materials, show compelling intrinsic structural features, e.g., the highly crystalline nature and designable and tunable porosity, as well as tailorable functionality, rendering them suitable for proton ...

Noncoplanarity in proton-proton bremsstrahlung

Physical Review C, 2001
Using the soft-photon approximation, we address the issue of the importance of noncoplanarity effects in proton-proton bremsstrahlung, We investigate the noncoplanar cross section as a function of the noncoplanarity angle (φ) over bar for the entire range of the photon polar angle psi(gamma).

Collective proton transport with weak proton-proton coupling

Physical Review E, 2000
A mechanism based on the peculiar dynamical properties of the hydrogen bond is suggested to describe fast proton transfers in hydrogen-bonded chains with realistic (weak) intersite proton-proton interactions. For this purpose, a two-sublattice model is suggested and studied analytically that admits an exact soliton solution.

Effect of Imidazole Arrangements on Proton-Conductivity in Metal-Organic Frameworks.

Journal of the American Chemical Society, 2017
Imidazole molecules were frequently incorporated into porous materials to improve their proton conductivity. To investigate how different arrangements of imidazoles in metal-organic frameworks (MOFs) affect the overall proton conduction, we designed and ...

Theory of Proton-Proton Bremsstrahlung

Physical Review, 1966
The proton-proton bremsstrahlung cross section is derived to first order in the electromagnetic interaction and the nucleon-nucleon $t$ matrix. The cross section is expressed in terms of the nucleon-nucleon phase shifts and the quasi-phase parameters needed to describe $t$ off the energy shell. The formulas are given in a form suitable for calculation.

Proton–proton correlations observed in two-proton radioactivity of 94Ag

Nature, 2006
The stability and spontaneous decay of naturally occurring atomic nuclei have been much studied ever since Becquerel discovered natural radioactivity in 1896. In 1960, proton-rich nuclei with an odd or an even atomic number Z were predicted to decay through one- and two-proton radioactivity, respectively.
