介质辅助的低能核聚变

Medium Assisted Low Energy Nuclear Fusion

Pankaj Jain, Harishyam Kumar

AI总结:

本研究采用二阶含时微扰理论探究介质辅助低能质子-镍核聚变,发现特殊原子构型可大幅提升反应速率,间距无需极精细调谐但偏离过大会使速率骤降,该结论或可解释相关实验的成败差异。

摘要:

我们采用二阶含时微扰理论研究了低能条件下介质中的核聚变过程。我们聚焦于低能质子与镍核发生聚变的特定过程,该反应分两步或两次相互作用进行,我们将对应这两次相互作用的振幅分别称为分子矩阵元和核矩阵元:第一个振幅涉及与介质中另一原子核的库仑相互作用,第二个则对应核聚变过程本身。此前的论文已表明,这类二阶过程的振幅可忽略不计,除非有特殊的介质效应提供辅助。在本论文中,我们证实存在一种特殊的原子构型,可大幅增强该过程。我们发现,若能调节原子间的间距,反应速率可得到充分提升,达到易于观测的水平。这种间距并不需要极度精细的调谐,但如果间距偏离显著,反应速率会急剧下降至可忽略的水平。这或许也能解释众多研究该现象的实验者所经历的成功与失败。我们仅研究了涉及单光子发射的一种特定末态,但我们表明,还存在许多无需涉及光子发射的可能末态。

英文摘要:

We study the process of nuclear fusion at low energies in a medium using the second order time dependent perturbation theory. We consider a specific process which involves fusion of a low energy proton with a Nickel nucleus. The reaction proceeds in two steps or interactions. We refer to the amplitudes corresponding to these two interactions as the the molecular and the nuclear matrix elements. The first amplitude involves Coulomb interaction with another nucleus in the medium while the second corresponds to the nuclear fusion process. It has been shown in earlier papers that such a second order process has negligible amplitude unless it is assisted by special medium effects. In the present paper we show the presence of a special configuration of atoms which greatly enhances the process. We find that if the spacings among the atoms can be tuned, the rate can be sufficiently enhanced so that easily observable. The spacings do not require acute fine tuning, however, if they are significantly off the rate falls sharply to negligible values. This might also explain both the successes and failures experienced by many experimentalists studying this phenomenon. We study only a particular final state which involves emission of one photon. However we show that many final states are possible which need not involve photon emission.
