Rate Coefficient Determination in Charge Transfer Reactions
The development of experimental ion-trap techniques provides the opportunity to compare directly theoretical rate coefficients to experimental data in the low-temperature regime. In the present work, we consider the ion-atom collisional systems, N, O, Si and Si on a He target, in order to examine the present status of the agreement between theory and experiment.
متن کاملUsing the Power-Law Rate Expression for Assessment of Rate Data and Detection of Infeasible Mechanisms for Reversible Reactions
A procedure for analysis of experimental data and model discrimination in regression of rate data of reversible, heterogeneous reactions which uses the power-law rate expression is described. The numerical values of the power-law parameters are calculated first by regression of the experimental data. These parameters are used to assess whether the quality of the experimental data is sufficient ...
متن کاملBack-reaction effects in power-law inflation
I consider a power-law inflationary model taking into account back-reaction effects. The interesting result is that the spectrum for the scalar field fluctuations does not depends on the expansion rate of the universe p and that it result to be scale invariant for cosmological scales. However, the amplitude for these fluctuations depends on p. Pacs numbers: 98.80.Cq An inflationary phase elimin...
متن کاملDeterministic reaction models with power-law forces
We study a one-dimensional particles system, in the overdamped limit, where nearest particles attract with a force inversely proportional to a power α of their distance and coalesce upon encounter. The detailed shape of the distribution function for the gap between neighbouring particles serves to discriminate between different laws of attraction. We develop an exact Fokker-Planck approach for ...
متن کاملBarrierless reactions between two closed-shell molecules. I. Dynamics of F(2)+CH(3)SCH(3) reaction.
A detailed experimental and theoretical investigation of the first-reported barrierless reaction between two closed-shell molecules [J. Chem. Phys. 127, 101101 (2007)] is presented. The translational energy and angular distributions of two product channels, HF+CH(2)SFCH(3) and F+CH(3)SFCH(3), determined at several collision energies, have been analyzed to reveal the dynamics of the studied reac...
