Radioactive Ion Beams in Nuclear Astrophysics,of Science which is still in its infancy, but which is currently attracting an increasing interest [Buc85a, Kub89, Mye90, McC90, Obe90]. Very few RIB with the ranges of energies and intensities needed for studying nuclear reactions of astrophysical interest have been produced so far [Dar90a, Dar90b]作者: 神刊 時(shí)間: 2025-3-25 04:18
Direct Reaction Mechanism in Astrophysically Relevant Processes,ions not only power the energy production in stars, but they are also responsible for the concept of nucleosynthesis, i.e. the creation of the elements. Theoretical models for the description of these nuclear processes are essential because in most cases it is not possible to determine reaction rate作者: Ataxia 時(shí)間: 2025-3-25 10:14
,Nuclear Reaction Rates — from Laboratory Experiments and in the Stellar Plasma,the abundancies of the elements and their isotopes as we observe them in nature.

Production of Heavy Elements in Inhomogeneous Cosmologies,t was roughly 10 .s old. If this change is due to a first order phase transition, baryon density inhomogeneities can be produced and survive until nucleosynthesis. At that point they can affect the primordial abundances resulting from element formation in the early universe. In this article we under作者: 爭吵加 時(shí)間: 2025-3-26 04:40

,Nuclear Reaction Rates — from Laboratory Experiments and in the Stellar Plasma,h lower total mass, thus simultaneously creating new elements. It is therefore not surprising that studies of stellar evolution require as input the reaction rates for those nuclear processes which are part of the network of many nuclear reactions taking place at each stage of stellar evolution.作者: 滲透 時(shí)間: 2025-3-26 23:23
Primordial Nucleosynthesis: Beyond the Standard Model,t, and otherwise unattainable, constraints on many aspects of particle physics. Finally, there is tentative evidence which suggests that the Standard Big Bang (SBB) model is incorrect in that it cannot reproduce the inferred primordial abundances for a single value of the baryon-to-photon ratio.作者: Airtight 時(shí)間: 2025-3-27 03:33 作者: 裂隙 時(shí)間: 2025-3-27 09:06

Nuclei in Cosmic Rays,some 50 km east of Berlin [Hes12]. The results of the measurements during this flight showed unambiguously that the ionization of air passed through a flat minimum between 1000 and 2000 m above ground and then increased steeply to values much above ground level. This clearly indicated an extraterrestrial source of radiation.作者: motor-unit 時(shí)間: 2025-3-28 12:51
