Dynamical screening of an atom confined within a finite-width fullerene

Dynamical Screening of an Atom Confined within a Finite-Width Fullerene

This is an investigation on the dynamical screening of an atom confined within a fullerene of finite width. The two surfaces of the fullerene lead to the presence of two surface plasmon eigenmodes. It is shown that, in the vicinity of these two frequencies, there is a large enhancement of the confined atom’s photoabsorption rate. PACS numbers: 32.80.Fb, 36.40.Gk, 36.40.Vz Submitted to: J.

An analysis of electromagnetic scattering from finite-width strips

Leak Width of a Cusp-Confined Plasma

The theoretical and numerical steady-state calculation of the width of an escaping plasma stream through a magnetic mirror solves the self-consistent potential and charge distribution for a low beta plasma. The leak width is obtained as the geometric mean of the ion and electron Larmor radius, also called hybrid width, in agreement with some experimental measurements. If the out-streaming plasm...

The Nitrogen atom effect on structural and magnetic properties of Fullerene C20:A DFT study

The fullerene structures of C20cage and bowl,C20H10 and their N-doped structures as C20cage NH,C20bowl NH, C20H10NH, C20H10N and their isomers are optimized using the MPW1PW91/6-31G level of the theory. Magnetic shielding tensors of 14N and 13C atoms are calculated by the same level of the theory. Results show that doping an N atom on fullerenes affects differently on the chemical shielding of ...
