正电子素受体反应的温度、压力和溶剂依赖性
Temperature, Pressure & Solvent Dependence of Positronium Acceptor Reactions
摘要：
正电子素（Ps）与弱受体（Ac）的反应速率（k）导致形成Ps-Ac络合物，其表现出几个有趣的特征：k的非单调温度依赖性（偏离通常的Arkenius范式），k相对于不同溶剂的相当大的可变性，以及在环境温度下对外部压力的响应的异常（在某些介质中k变化很大，而在其他介质中几乎没有变化）。我们解释了所有这些现象，通过引入的临界表面张力，统一的意见，在不同的非极性溶剂在不同的温度和压力的新概念。
英文摘要：
Positronium (Ps) reaction rates (k) with weak Acceptors (Ac) leading to the formation of Ps-Ac Complexes show several intriguing features: non-monotonic temperature dependence of k (departing from the usual Arrhenius paradigm), considerable variablity of k with respect to different solvents, and anomalies in response to external pressure at ambient temperature (large changes of k in some media and hardly any in others). We explain all these phenomena, through the introduction of the novel concept of a critical surface tension, which unifies observations in diverse non-polar solvents at different temperatures and pressures.
