Exotic atoms and their electron shell

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 1994
Abstract Progress in the field of exotic atoms seems to increase proportionally with the number of exotic atoms produced and the increase in energy resolution with which the transition energies are determined. Modern experiments use high resolution crystal spectrometers or even aim at laser spectroscopy.

Atomic modelling of nova shells

Astrophysics and Space Science, 1995
Atomic models developed by the author and used to interpret the spectra of cool shells from old classical novae are reviewed. Some of the remaining problems relating to the spectra are discussed briefly. The use of these data in photoionization models is described, and the evolution of nova shells is discussed.

Atomic structure and ultrastructure of the Murex troscheli shell

Journal of Structural Biology, 2012
The structure of the gastropod Murex troscheli shell was investigated by using high-resolution scanning and transmission electron microscopies and high-resolution synchrotron X-ray powder diffraction. Rietveld refinement of X-ray diffraction patterns revealed anisotropic distortions of the orthorhombic aragonite unit cell, reaching a maximum of about 0.

Lattice of Shell-Model Atoms

1972
In this section the equations of equilibrium are derived for a monatomic, one-dimensional lattice of the Cochran type [13] based on the Dick-Overhauser [12] shell-model of the atom: a core, comprising the nucleus and inner electrons, surrounded by a shell of outer electrons.

Atomic processes in nova shells

1990
The unusual spectra of the spatially-resolved nova shells of DQ Her, T Aur and CP Pup are reviewed. Because calculations for these conditions have not been made, recombination models of HI, HeI and CNO from a neutral to a doubly ionized state were constructed. The models are described and the results presented for densities at various temperatures.
