The Size of the Electron.

Authors: Brian Strom
Comments: 15 Pages.

The structure of the atom is analyzed using the results of established experiments on ionization energies and spectral emissions. Ionization energy levels - when electrons are energized to escape from the Potential Energy Well of the atom – show distinct patterns. The depth of the Potential Energy Well is directly proportional to the number of protons in the nucleus, but is not dependent on the number of neutrons. The ionization energies, and therefore the electron depths, are similar to those of a "multi-layered ball" of electrons, as if they simply fill the three-dimensional Potential Energy Well around the nucleus. The electrons appear to be loosely-packed for the lighter elements, and more tightly-packed for the heavier elements. The electrons appear to be much larger than we presently imagine.

Two-Proton Knockout Cross Section ${\sigma}_{-2p} (^{44}S \rightarrow ^{42}{si})$: Strong Evidence of Magicity and Sphericity of $^{42}_{14}si_{28}$

The issue of whether $^{42}_{14}Si_{28}$ is doubly magical or not has been a contentious one. Fridmann {\it et al.} (Nature 435 (2005) 922) through studies of two-proton knockout reaction $^{44}_{16}S_{28} \rightarrow ^{42}_{14}Si_{28}$, presented a strong empirical evidence in support of magicity and sphericity of $^{42}_{14}Si_{28}$. However in complete conflict with this, Bastin {\it et al.} (Phys. Rev. Lett. 99 (2007) 022503) gave equally strong empirical evidences, to show that the N = 28 magicity had completely collapsed, and that $^{42}_{14}Si_{28}$ was a well deformed nucleus. At present the popular consensus (Gade {\it et al.}, Phys. Rev. Lett. 122 (2019) 222501) strongly supports the latter one and discards the former one. Here, while we accept the latter experiment as being fine and good, through a careful study of an RMF model calculation, we show that actually the experimental results of Fridmann are also independently good and consistent. As per the Fridmann experiment, the sphericity and magicity of $^{42}_{14}Si_{28}$ is manifested only through proton number Z=14 being a strong magic number, while the neutron magic number N=28 disappears (or goes into hiding); and still this nucleus is spherical. This is a new and amazing property manifesting itself in this exotic nucleus $^{42}_{14}Si_{28}$. In this paper we provide a consistent understanding of this novel reality within a QCD based model. This model, which has been successful in explanation of the halo phenomenon in exotic nuclei, comes forward to provide the physical reason as to why the Fridmann experiment is correct. This QCD based model shows that it is tritons, as elementary entity making up $^{42}_{14}Si_{28}$, which then provides consistency to the above amazing conclusions arising from the Fridmann experiment.

Anticipated Nuclear Experiment

Authors: George Rajna
Comments: 66 Pages.

The precise determination of the neutron skin of lead (or how far the neutrons stick out from the protons in the nucleus) tells us about the equation of state (EOS) of neutron matter. [38] Matter is composed of chemical elements mainly created in stars via nuclear reactions and complex nuclear reaction networks. [37] These particles are produced by stellar flares or by shock waves driven by magnetic events in the stellar corona. [36] Researchers have investigated wave-particle interactions between energetic electrons and chorus waves evolving in the space surrounding the Earth using the scientific satellite Arase and, simultaneously, transient auroral flashes by the ground-based global observation network. [35] The universe consists of a massive imbalance between matter and antimatter. [34] Our universe could be the mirror image of an antimatter universe extending backwards in time before the Big Bang. [33] "As you celebrate New Year's Day, cast an eye upward and think for a moment about the amazing things our country and our species can do when we set our minds to it," Stern wrote in the New York Times on Monday. [32] Our senses are stuck in the past. There's a flash of lightning, and then seconds pass until we hear the rumble of distant thunder. We hear the past. [31] ESA's technical centre in the Netherlands has begun running a pulsar-based clock. The "PulChron' system measures the passing of time using millisecond-frequency radio pulses from multiple fast-spinning neutron stars. [30] VR is an almost perfect avenue for this approach, since it has been surging in popularity as both entertainment and an educational tool. [29] Using MAGIC telescopes and NASA's Fermi spacecraft, an international team of astronomers has discovered a new source of very high energy gamma-ray emission around the supernova remnant (SNR) G24.7+0.6.
