The Shell Vectorial Model

2007
By resorting to the principles of quantum mechanics and after having dealt with specific atoms, one can now proceed to the description of the electronic structure in generic multi-electron atoms. We shall see that the sequence of electron states accounts for the microscopic origin of the periodic Table of the elements.

Pairings in the shell model (III)

Nuclear Physics, 1961
Abstract (1) The Casimir operators in U Ω , SU Ω and Sp Ω are explicitly given, so that the relation of the pairing forces to these operators can be seen easily. (2) As a result, it is clearly shown that the pairing forces for a specific case of the intermediate pairing scheme (the normal case in sect. 2) as well as those for the L - S and the j

MULTI-MAJOR-SHELL SHELL MODEL FOR HEAVY NUCLEI–AN EXTENDED PROJECTED SHELL MODEL

International Journal of Modern Physics E, 2008
The projected shell model (PSM) in its original version is an efficient shell model truncation scheme for well deformed nuclei. However, the model is applicable only to rotational motion, but not collective vibrations. In this paper, we discuss a scheme that extends the PSM applicability to low-lying rotational and vibrational states possibly in all ...

A discrete model of thin shells

ACM SIGGRAPH ASIA 2008 courses on - SIGGRAPH Asia '08, 2005
We present a discrete model for the behavior of thin flexible structures, such as hats, leaves, and aluminum cans, which are characterized by a curved undeformed configuration. Previously such models required complex continuum mechanics formulations and correspondingly complex algorithms.

Shell PCA: Statistical Shape Modelling in Shell Space

2015 IEEE International Conference on Computer Vision (ICCV), 2015
In this paper we describe how to perform Principal Components Analysis in "shell space". Thin shells are a physical model for surfaces with non-zero thickness whose deformation dissipates elastic energy. Thin shells, or their discrete counterparts, can be considered to reside in a shell space in which the notion of distance is given by the elastic ...
