首次报道了用纳秒脉冲3 MeV质子在水中产生的电子水溶液的产率随时间变化的直接观测。根据加入的氢氧根离子的影响，估计G（e-aq）在10-11 s时至少为3.6，在10-9 s时下降到2.3。实验测量不同意本扩散模型的预测，修改，以改善模型进行了讨论。
Direct observation of the time dependence of the yield of e–aq produced in water by nanosecond pulses of 3 MeV protons is reported for the first time. From the effect of added hydroxide ion, G(e–aq) is estimated to be at least 3.6 at 10–11 s, falling to 2.3 at 10–9 s. The experimental measurements do not agree with predictions of the present diffusion model; modifications to improve the model are discussed.
