Protonated and Cationic Helium Clusters
Molecules, 2020 Protonated rare gas clusters have previously been shown to display markably different structures compared to their pure, cationic counterparts. Here, we have performed high-resolution mass spectrometry measurements of protonated and pristine clusters of ...

Proton–proton, anti-proton–anti-proton, proton–anti-proton correlations in Au + Au collisions measured by STAR at RHIC [PDF]
The European Physical Journal C, 2006 The analysis of two-particle correlations provides a powerful tool to study the properties of hot and dense matter created in heavy-ion collisions at ultra-relativistic energies. Applied to identical and non-identical hadron pairs, it makes the study of space-time evolution of the source in femtoscopic scale possible.

A gated strategy stabilizes room‐temperature phosphorescence
Aggregate, 2023 Room‐temperature phosphorescence (RTP) of purely organic materials is easily quenched with unexpected purposes because the excited triplet state is extremely susceptible to external stimuli.

Synthesis, Characterization and Protonation Behavior of Quinoxaline-Fused Porphycenes
Molecules, 2017 9,10-Quinoxaline-fused porphycenes 1a-H2 and 1b-H2 were synthesized by intramolecular McMurry coupling. As a result of the annulation of the quinoxaline moiety on the porphycene skeleton, 1a-H2 and 1b-H2 display absorption and fluorescence in the near ...

On the Equality of the Proton-Proton and Proton-Neutron Interactions [PDF]
Physical Review, 1939 A comparison of the 1S proton-proton interaction and the 1S proton-neutron interaction has been made recently by Breit, Hoisington, Share, and Thaxton. It is the purpose of this letter to add a remark to the subject. With the meson type of potential, [C x e^(-lambda x r)]/r x lambda, a variational calculation has been made of the binding energy of H3 ...

Role of Thr82 for the unique photochemistry of TAT rhodopsin
Biophysics and Physicobiology, 2021 Marine bacterial TAT rhodopsin possesses the pKa of the retinal Schiff base, the chromophore, at neutral pH, and photoexcitation of the visible protonated state forms the isomerized 13-cis state, but reverts to the original state within 10–5 sec.

Nuclear Physics B, 1967 Abstract We calculate proton-proton Bremsstrahlung cross sections using the Tabakin separable potentials to generate off-shell nucleon-nucleon t-matrix elements in low partial waves and off-shell one-pion-exchange amplitudes for the higher partial waves.

E-Journal of Chemistry, 2007 The protonation constants of diamines such as ethylenediamine, 1,2-diaminopropane, 1,3-diaminopropane, o-phenylenediamine, m-phenylene-diamine, p-phenylenediamine were determined on the basis of Bjerrum and Calvin method in methanol-water mixtures.

The leading proton effect in proton-proton collisions
Nuclear Physics B, 1973 Abstract The p spectrum data in the range s = 28 to s = 1995 are described with the triple Regge formula. The behaviour of the various couplings at small | t | is explored. It is found that the non-scaling terms, at s ≅ 400 GeV 2 remove the turnover expected if the triple pomeron vanishes at t = 0.
