The physical states of Fermi systems

A classification of all translationally invariant states over the algebra of anticommutation relations which satisfy criteria of finite mean density, finite mean kinetic energy, and finite mean entropy is given. It is demonstrated that these concepts can be discussed in terms of affine, semi-continuous, functionals which respect the barycentric decompositions of invariant states. Many other pertinent results, both local and global, are derived.

Mass Spectrometry: The Shapes of “Meta-Stable Peaks”

The effect on the shape of “metastable peaks” arising from decompositions throughout the whole flight path in a mass spectrometer is considered. The effects of discriminations against product ions are calculated; the effects of finite beam dimensions, angular spreading and kinetic energy of separation of fragments during the decomposition are discussed theoretically and illustrated by practical examples.
