最近发展的γ-诱导正电子能谱（GiPS）装置显着扩展的适用性的动量相关技术（AMOC）的研究散装样品。与传统的正电子湮没实验相比，该方法具有许多优点，如在容器壁中的湮没率极低、不需要正电子源以及正电子在容器壁中的湮没等。这种方法在液态水的情况下得到了验证，液态水被认为是正电子和正电子素化学中的参考介质。
Recent development of the Gamma-induced Positron Spectroscopy (GiPS) setup significantly extends applicability of the Age-Momentum Correlation technique (AMOC) for studies of the bulk samples. It also provides many advantages comparing with conventional positron annihilation experiments in liquids, such as extremely low annihilation fraction in vessel walls, absence of a positron source and positron annihilations in it. We have developed a new approach for processing and interpretation of the AMOC-GiPS data based on the diffusion recombination model of the intratrack radiolytic processes. This approach is verified in case of liquid water, which is considered as a reference medium in the positron and positronium chemistry.
