摘要:

我们讨论了由不同浓度的中子到质子驱动的核相变的实验证据。不同的中子与质子浓度比导致不同的相变临界点。这类似于4 He-3 He液体混合物中发生的相变。我们提出的实验结果,揭示了N/A(或Z/A)的依赖性的相变和讨论这些观察的关键现象的朗道自由能描述的可能影响。

英文摘要:

We discuss experimental evidence for a nuclear phase transition driven by the different concentration of neutrons to protons. Different ratios of the neutron to proton concentrations lead to different critical points for the phase transition. This is analogous to the phase transitions occurring in 4He-3He liquid mixtures. We present experimental results which reveal the N/A (or Z/A) dependence of the phase transition and discuss possible implications of these observations in terms of the Landau Free Energy description of critical phenomena.
