Modelling low-energy electron–molecule capture processes

Modelling low-energy electron–molecule capture processesw

Cross sections and rate coefficients for capture of low-energy electrons with polar and polarizable target molecules are calculated in the framework of Fabrikant and Hotop’s extended version of the Vogt–Wannier model and an extension of this approach is given in the present article. Analytical approximations are derived in order to facilitate the application to experiments. A comparison with a ...

Techno-economic modelling and cost functions of CO2 capture processes

The paper contributes to techno-economic modelling of CO2 capture process in coalfired power plants. Technological options of CO2 capture have been chosen and cost estimation relationships (CERs) for the chosen options provided. The CERs are being fitted into a developed overall model of carbon capture and sequestration. Functions relating capital costs, operation and maintenance costs and tota...

Low-energy electron capture by Ne2+ ions from H(D)

Using the Oak Ridge National Laboratory ORNL ion-atom merged-beams apparatus, the absolute, total single-electron-capture cross section has been measured for collisions of Ne2+ with deuterium D at centerof-mass c.m. collision energies of 59–949 eV/u. With the high-velocity ion beams now available at the ORNL Multicharged Ion Research Facility, we have extended our previous merged-beams measurem...

Matrix Elements for Low-Energy p-d Radiative Capture

The radiative capture reaction p 1 d ! 3He 1 g has been the focus of many experimental and theoretical studies over the past 20 years, and during this time experiments with polarized protons and deuterons have come to be fairly common. Initially, the interest in polarization experiments arose in part from the observation that the “tensor analyzing powers” for p-d capture are sensitive to D-stat...
