Stellar Origin of Layered Nuclear Bond Structures

Abstract: The structure of most nuclei may be considered as concentric layers of  alpha particles bound together by very strong short-range nuclear bonds.

Evolution is a chaotic process in which only the fittest survive. This is particularly true in the synthesis of nuclei in the incredibly dense and hot cores of stars and exploding supernovae – that is, in the cauldrons of the cosmos. Inspection of the properties of the 92 natural elements indicates that the origin of the structure of their most stable and abundant isotopes may be explained in terms of the interaction of the strong and electro-weak nuclear forces. Whereas the strong nuclear force has a very short-range acting only between contiguous nucleons the electro-weak force has a much greater range.

Topics:
1. Nuclear Bond Structure
2. Helium synthesis in the Sun.
3. Carbon synthesis in Giant stars.
4. Carbon-Nitrogen-Oxygen cycle in Giant stars.
5. Synthesis of the first 28 elements in Supergiant stars
6. Supernovae synthesis of all 92 elements.

Layered Nuclear Bond Structure

Abstract: Some of the most stable and abundant nuclei are successfully modeled as dense closed layers of alpha particles. The first three layers are gradually formed in hot stellar cores whereas the outer three layers and a strengthening neutron skin are rapidly added in supernovae.

Bonding in molecular states of light even-even nuclei

Abstract: This analysis of the bonding in the excited molecular states of 12C, 16O, 20Ne, 24Mg, 28Si and 32S as proposed by Ikeda is based on the concept of meson bonds. This shows a very regular variation in the bonding between alpha particles in each nucleus as the excitation energy changes. Furthermore, the most excited state of each nucleus is shown to be less strongly bound than are less excited states.

Models of the meson bond structures of the most abundant products of stellar nucleosynthesis

Abstract: Models of the bond structure of the most abundant products of stellar nucleosynthesis based on Bernal’s models of dense liquid drops are related to the relevant nuclear binding energy data and shell models. It is shown that good agreement is obtained when alpha particles are considered to be the densely packed hard spheres of Bernal’s models.
