Elastic scattering of low-energy positron by atom

Selective Oxidation of Sulfides in Flow Chemistry

“…Sulfoxides are very important moieties widely used in the preparation of biologically and pharmaceutically significant compounds. They constitute a relevant motif in marketed therapeutics, such as Provigil [1] and Nexium [2] and in biologically active components of garlic extracts such as Allicin and Ajoene [3] (Figure 1). Sulfide oxidation has also been utilized in the extraction of sulfur-containing compounds from crude oil via catalytic oxidative desulfurization processes.…”

Positron scattering and annihilation on noble-gas atoms

“…This study accounted for polarization of the target by the positron and demonstrated the importance of virtual Ps formation by using a rather crude approximation (see also [18]). This approximation was also used in subsequent studies for helium and other noble-gas atoms [19,20]. A more sophisticated approximation to the virtual Ps contribution was developed and applied to positron scattering, binding and annihilation in Refs.…”

Spin polarization and differential cross-sections for e^±-scattering from rhenium atom

“…This aspect of electron and positron scattering from heavy atoms has been further examined by Neerja et al [24][25][26]. Recently, Nikolić and Tančić and Harish Mohan et al [27][28] studied the low energy elastic scattering of positrons by inert target.…”
