The Proton-Proton Interaction [PDF]
Physical Review, 1950 This paper presents a phenomenological analysis of the proton-proton scattering observed at 32 and 340 Mev in terms of static nuclear potentials. Comparison of these results with the neutron-proton scattering at 40, 90, and 280 Mev analyzed previously indicates that nuclear forces are not charge independent. In particular, there is definite evidence in

Polarized Proton-Proton Bremsstrahlung [PDF]
Physical Review Letters, 1986 Abstract A proton-proton bremsstrahlung experiment recently carried out at TRIUMF with polarized protons gives results which disagree with the Soft Photon Approximation and agree with potential model calculations.

Search for sphalerons in proton-proton collisions [PDF]
Journal of High Energy Physics, 2016 In a recent paper, Tye and Wong (TW) have argued that sphaleron-induced transitions in high-energy proton-proton collisions should be enhanced compared to previous calculations, based on a construction of a Bloch wave function in the periodic sphaleron potential and the corresponding pass band structure.

Molecules, 2022 The introduction of an electron-donating triphenylamine motive into a 2,2′,6′,2′′-terpyridine (terpy) moiety, a cornerstone molecular unit in coordination chemistry, opens new ways for a rational design of photophysical properties of organic and ...

Protonation of maleic and fumaric acid in aqueous sulfuric acid solutions [PDF]
Journal of the Serbian Chemical Society, 2000 The protonations of maleic and fumaric acid in an acidic medium (aqueous solutions of sulfuric acid) were followed spectrophotometrically at room temperature. The acid-base equilibria were characterised qualitatively and quantitatively.

Cancers, 2015 In addition to the physical advantages (Bragg peak), the use of charged particles in cancer therapy can be associated with distinct biological effects compared to X-rays. While heavy ions (densely ionizing radiation) are known to have an energy- and charge-dependent increased Relative Biological Effectiveness (RBE), protons should not be very ...

Acta Crystallographica Section E: Crystallographic Communications, 2017 The title compound, (C15H14N3)[NiCl4]Cl, comprises an NiII cation tetrahedrally coordinated by four chloride anions, a non-coordinating chloride anion and an essentially planar terpyridinium trication (tpyH33+), in which the central pyridinium ring forms

The rate of the proton-proton reaction
The Astrophysical Journal, 1994 We re-evaluate the matrix element for the proton-proton reaction which is important for stellar-evolution calculations and for the solar-neutrino problem. We self-consistently determine the effect of vacuum polarization on the matrix element by first correcting the low-energy scattering data to account for vacuum polarization.

Journal of Natural Fibers, 2023 Chitin is one of the most abundant biopolymers in nature. Herein, we report the successful preparation of chitin nanofibers (ChNFs) from shrimp shell waste using a partial deacetylation process with NaOH and high-speed blending.
