The shell structure of magic nuclei far from stability is discussed in terms of the self-consistent spherical Hartree-Fock-Bogoliubov theory. In particular, the sensitivity of the shell-gap sizes and the two-neutron separation energies to the choice of particle-hole and particle-particle components of the effective interaction is investigated.

The spectral statistics of low–lying states of f p shell nuclei are studied by performing large shell–model calculations with a realistic nuclear interaction. For Ca isotopes, we find deviations from the predictions of the random–matrix theory which suggest that some spherical nuclei are not as chaotic in nature as the conventional view assumes.

Calcination of lysozyme-silica hybrid hollow particles gives novel cage-like hollow spherical silicas with differently patterned through-holes on their shell structure.

The TIEL benchmarks include a set of analytical benchmark solutions to the transport equation in infinite media. In this paper, we present solutions for the infinite planar, point, spherical shell, and solid spherical sources solved using the PENTRAN 3-D Parallel SN code compared to reference solutions of the TIEL benchmark problems. Excellent agreement (less than 0.7% difference) was achieved ...

A two-layer spherical alpha2 dynamo model consisting of an inner electrically conducting core (magnetic diffusivity lambdai and radius ri) with alpha=0 surrounded by an electrically conducting spherical shell (magnetic diffusivity lambdao and radius ro) with a constant alpha is shown to exhibit oscillatory behavior for values of beta=lambdai&solm0;lambdao and ri&solm0;ro relevant to the solar d...

Observations of novae at radio frequencies provide us with a measure of the total ejected mass, density profile, and kinetic energy of a nova eruption. The radio emission is typically well characterized by the free–free emission process. Most models to date have assumed spherical symmetry for the eruption, although for as long as there have been radio observations of these systems, it has been ...

A Thomas-Fermi model of a spherical shell of positive charge is investigated, under various boundary conditions. The electron distribution and the ionization charge are given particular attention.

Modern mechanical engineering sets the tasks of calculating thin-walled structures that simultaneously combine sometimes mutually exclusive properties: lightness and economy on one hand high strength reliability other. In this regard, use orthotropic materials plastics seems quite justified.The article demonstrates complex representation method equations shells general theory, which allowed in ...
