Remarkable Properties of Isotope Effect

Present paper is devoted to the non - accelerator manifestation of the strong nuclear interaction - the heart of quantum chromodynamics (QCD) which is part of the Standard Model (SM). The observation of isotopic shift (0.103 eV) of the zero - phonon emission line in photoluminescence spectra of LiD crystals (possessing a strict interaction in the deuterium nucleus) comparison with LiH (in the hydrogen nucleus of which there is no strong interaction) is a first direct proof of the strong nuclear long - range character. The non - accelerating measurement of the strong interaction constant from the distance between nucleons made it possible to find the maximum possible value of αs = 2.4680. The isotopic acquisition of mass by massless fermions is briefly discussed

Nuclear Structure and Stability Arise from Alternating Quarks within Light Nuclei

<div> <div> <p>The atomic nucleus is made of protons and neutrons, each comprising a mix of 3 up or down quarks. No consensus exists for nuclear structure from among the 30+ proposed models of the atomic nucleus, although they generally agree that quarks play no role. The light nuclides of interest to nuclear fusion exist in a purgatory of uncertainty, wanting not only for structure but also for some insight into their erratic sizes. The deuterium nucleus is twice the mass of the proton but 2.5 times larger. In fact, deuterium is larger than either tritium or helium-4. The lithium-7 nucleus is larger than all of these, yet smaller than lithium-6. Here we show that an alternating quark model (AQM) predicts these erratic nuclear radii to within 99% of experimental (SD 2.5%). The distance between sequential quarks is constant and equal to the radius of the proton. Quark structures assume simple geometries. Alternating quarks predict nuclear stability, the height of the Coulomb barrier, near-range attraction, and far-range repulsion. Through the lens of nonlinear dynamics, quarks behave as linked harmonic oscillators traveling within a basin of attraction. This satisfies the uncertainty principle while allowing localization of an average quark position. The alternating quark model thus represents an intersection between chaos theory and quantum mechanical uncertainty.<br></p> </div> </div>

Non - Accelerator Observation of the Long - Range Strong Nuclear Interaction

The non - accelerator observation of the long - range strong nuclear interaction is presented. We have studied the low - temperature spectra (reflection and luminescence) of the LiH (without strong interaction in hydrogen nucleus) and LiD (with strong interaction in deuterium nucleus) crystals which are different by term of one neutron from each other. The experimental observation of isotopic shift (103 meV) of the phononless free excitons emission line in LiD crystals is a direct manifestation of the long - range strong nuclear interaction. Such conclusion is made to the fact that the gravitation, electromagnetic and weak interactions are the same in both kind crystals, it only emerges the strong interaction in deuterium nucleus. As far as Born - Oppenheimer approximation does not work in isotope effect, we tentative connect our experimental observation with long - range hadron - lepton interaction. Most important study of the LiHx D1-x mixed crystals is the first measurement of the long - range force dependence of strong nuclear interaction on the distance between nucleons in deuterium nucleus

Messung der kohärenten Streuamplitude für die Neutron-Deuteron- Wechselwirkung am Neutronenschwerkraftrefraktometer des FRM / Measurement of the n-d Coherent Scattering Amplitude Using the Neutron Gravity Refractometer at the Research Reactor of the Technical University of Munich

Measurements of the coherent scattering amplitudes of various mixtures of heavy and light water are reported. By means of mirror reflection technique the coherent scattering amplitudes of the D2O and H2O molecule are determined to be 19.148±0.004 F and -1.679±0.004 F, respectively. Use of aH=-3.740±0.003 F, obtained by the same technique, yields aD=6.674±0.006 F as the bound scattering amplitude of the deuterium nucleus. This value disagrees with the widely accepted 6.21±0.04 F, reported by Bartolini et al. in 1968.
