“…However this assumption remains untested. While ps resolution experiments for laser-driven and ultrafast pulsed electron radiolysis [11][12][13] have called into question the validity of this equivalence, the absence of absolute timing in those experiments has prevented quantitative analysis for electron interactions [14]. Likewise for proton interactions in H 2 O, where irradiation induced dynamics are expected to be more pronounced due to significantly higher energy density, an absence of both ps resolution and absolute timing references have precluded any ultrafast tests of this assumption.…”

Real-Time Electron Solvation Induced by Bursts of Laser-Accelerated Protons in Liquid Water

Understanding the mechanisms of proton energy deposition in matter and subsequent damage formation is fundamental to radiation science. Here we exploit the picosecond (10 −12 s) resolution of laser-driven accelerators to track ultrafast solvation dynamics for electrons due to proton radiolysis in liquid water (H 2 O). Comparing these results with modeling that assumes initial conditions similar to those found in photolysis reveals that solvation time due to protons is extended by > 20 ps. Supported by magnetohydrodynamic theory this indicates a highly dynamic phase in the immediate aftermath of the proton interaction that is not accounted for in current models.

“…The experimental investigation of excess electrons in a liquid in a static field, for instance right below the threshold for plasma formation, can be performed with similar methods as applied in the absence of an external field. In these methods, the excess electrons are usually generated by means of radiolysis [164][165][166][167] or laser-induced ionization [150][151][152] with short beam pulses. The produced solvated or quasi-free electrons can be measured with synchronized optical methods, such as pump-probe transient absorption measurements, 159,168 timeresolved resonance Raman spectroscopy, 159 transient terahertz spectroscopy, 150 core-hole decay spectroscopy, 152 and the time-resolved optical interferometric technique described in Ref.…”

The interaction of plasma with liquids has led to various established industrial implementations as well as promising applications, including high-voltage switching, chemical analysis, nanomaterial synthesis, and plasma medicine. Along with these numerous accomplishments, the physics of plasma in liquid or in contact with a liquid surface has emerged as a bipartite research field, for which we introduce here the term "plasma physics of liquids." Despite the intensive research investments during the recent decennia, this field is plagued by some controversies and gaps in knowledge, which might restrict further progress. The main difficulties in understanding revolve around the basic mechanisms of plasma initiation in the liquid phase and the electrical interactions at a plasma-liquid interface, which require an interdisciplinary approach. This review aims to provide the wide applied physics community with a general overview of the field, as well as the opportunities for interdisciplinary research on topics, such as nanobubbles and the floating water bridge, and involving the research domains of amorphous semiconductors, solid state physics, thermodynamics, material science, analytical chemistry, electrochemistry, and molecular dynamics simulations. In addition, we provoke awareness of experts in the field on yet underappreciated question marks. Accordingly, a strategy for future experimental and simulation work is proposed.

“…The detecting system is based on the transient absorption spectroscopy with a probe light ranging from 380 nm to 1500 nm [ 19 ]. Similar picosecond pulse radiolysis facilities have been established over the world, such as Laser Electron Accelerator Facility (LEAF) at Brookhaven National Laboratory, Linear Accelerator (LINAC) facility at Tokyo University, etc., and many of them have reached their full capacity [ 20 , 21 , 22 ]. Therefore, this unique time resolved technique based on high energy electron pulse enables us, although not ideally, to explore the ultrafast chemical reactivity of H 2 O •+ through the scavenging method in a variety of highly concentrated aqueous solutions.…”

Oxidation reactions by radicals constitute a very important class of chemical reactions in solution. Radiation Chemistry methods allow producing, in a controlled way, very reactive oxidizing radicals, such as OH•, CO3•–, NO3•, SO4•–, and N3•. Although the radical cation of water, H2O•+, with a very short lifetime (shorter than 1 ps) is the precursor of these radicals in aqueous solutions, its chemistry is usually known to be limited to the reaction of proton transfer by forming OH• radical. Herein, we stress situations where H2O•+ undergoes electron transfer reaction in competition with proton transfer.
