Measurement of muon transfer from proton to triton and pp micro molecular formation in solid hydrogen.
نویسندگان
چکیده
A new approach was used to study the reactions of muonic atoms and molecules in solid layers of hydrogen isotopes. Muons stopped in a pro-tium layer with a small admixture of tritium producing p atoms. Muon transfer from a proton to a triton generated t atoms which were emitted into a deuterium layer. Subsequent epithermal dtt molecular formation followed by dt fusion gave a prompt signal for the t emission. Fusion time spectra at various tritium concentrations were measured by detecting neutrons and particles and the p disappearance rates were determined. The rates of p ! t transfer and ppp formation were measured to be pt = model 10 6 s ?1 respectively. Comparisons are made with the most recent theoretical values.

This paper is a density functional theory (DFT) calculation of intramolecular proton transfer (IPT) in 6-hydroxypicolinic acid (6HPA, 6-hydroxypyridine-2-carboxylic acid) tautomeric forms. The transition state for the enol-to-keto transition is reported in the gas phase and in four different solvents. The planar and non-planar dimer forms of 6HPA keto and enol, respectively, were also studied i...

Four novel receptors were designed and synthesized for colorimetric detection of F− ions. The introduction of four electron withdrawing groups into the backbone of the receptors makes the two phenolic groups efficient hydrogen bonding sites. The binding properties of receptors with anions were examined for the first time by UV–Vis, 1H NMR and fluorescence spectroscopies. The addition of F− resu...
