Nuclear fusion in high density matter

B.J.B. Crowley1989年被引用 7Nuclear FusionIF 3出版社

Recent suggestions that nuclear fusion might be induced in ordinary matter at room temperature motivated this study of the processes that influence the reaction rate in highly compressed matter. An approximate model that applies in the regime of strongly coupled plasma (Γ > 1) is developed and used to estimate the rates of the nuclear reactions: d(p, γ) He3, in hydrogen of natural isotopic composition which has implications for energy generation within the giant planets, and the dd reactions under conditions that might be or might have been obtained in the laboratory. The conclusions do not support the recent claims that this reaction occurs, at observable rates, in small electrolytic cells and suggest that compressively induced fusion of hydrogen is likely to be of importance only in large dense systems as may be encountered in astrophysics.

最近の提唱、すなわち核融合が室温の通常物質において誘起されるかもしれないという示唆が、高圧縮物質における反応率に影響を及ぼす過程に関する本研究の動機となった。強結合プラズマ(Γ > 1)の領域に適用される近似モデルを開発し、それを用いて、巨大惑星内部でのエネルギー生成に示唆を与える天然同位体組成の水素中での核反応 d(p, γ) He3 の反応率と、実験室で実現される可能性または実現された可能性のある条件下での dd 反応の反応率を推定した。結論は、この反応が小型電解セルにおいて観測可能な速度で起こるという最近の主張を支持するものではなく、水素の圧縮誘起核融合は、天体物理学で遭遇するような大型で高密度の系においてのみ重要となる可能性が高いことを示唆している。
