Antigravitational Instability of Cosmic Substrate in the Newtonian Cosmology

Abstract

A new version of the forming Universe large-scale structures is proposed, based on the refuse of analyses of only the gravitational instability of the cosmological substrate. Vacuum, i.e. the dominant nonbaryonic matter in the Universe, creates the antigravitational instability of the baryonic cosmic substrate itself and causes the formation of galaxies.

Study of the nucleon radiative captures 8Li(n,γ)9Li, 9Be(p,γ)10B, 10Be(n,γ)11Be, 10B(p,γ)11C, and 16O(p,γ)17F at thermal and astrophysical energies

“…For this level the momentum J  = 5/2 -is given, 78 which allows one to take L = 1 for it, i.e., to consider it as a quartet 4 P 5/2 resonance at 0.261 (17) MeV in the laboratory system (l.s.). Its width of  cm = 100 (30) 8 Li scattering could not be found, several variants of the 4 S potential with the bound FS and different widths will be discussed.…”

“…In order to extract this constant from the available experimental data, let us consider information about spectroscopic factors S and A NC . The obtained results for A NC are listed in Table 8, in addition, we succeeded in finding a lot of data of spectroscopic factors of 17 F in the p 16 O channel, and therefore we present their values in the form of separate Table 9. …”

“…Since, there are no resonances of the negative parity in spectra of 17 F at the energy lower than 2.5 MeV; we will consider that 2 P potentials should to lead in this energy range practically to zero scattering phase shifts, and therefore they does not contain bound BSs, their depth can simple have a zero value.…”

“…The results in the field of study of thermonuclear proton capture reaction on 10 B at ultralow, i.e., astrophysical energies will be presented further. The possibility of description of the experimental data for the astrophysical S-factor of the proton radiative capture on 16 O to the ground state of 17 F was considered in the frame of the modified potential cluster model with forbidden states and classification of the states according to Young tableaux. It was shown that on the basis of the E1 transitions from the states of p 16 O scattering to the ground state of 17 F in the p 16 …”

“…In this case, as it was before, the MPCM is used as a nuclear model, which allows one to consider some thermonuclear processes, notably, radiative capture reactions of neutrons and protons on light nuclei, on the basis of unified views, criteria and methods. [40][41][42][43] Continuing study of thermonuclear reactions in the frame of the MPCM with FSs 36 let us consider the 16 O(p,) 17 F process, which takes part of the CNO cycle 37 and has additional interest, since it is the reaction at the last nucleus of 1p-shell with the forming of 17 F that get out its limit. As we usually assume, 37,38 the bound state (BS) of 17 F is caused by the cluster channel of the initial particles, which take part in the reaction.…”
