In a groundbreaking experiment, scientists have successfully captured the movement of electrons in real-time within liquid water, while simultaneously immobilizing the motion of the larger atom it orbits. This remarkable feat, akin to stop-motion photography, provides unprecedented insights into the electronic structure of molecules in the liquid phase, offering a glimpse into the immediate electronic response when a target is struck by an X-ray.
Published in the journal Science, the findings of this study mark a significant advancement in the understanding of the effects of radiation exposure on both objects and living organisms. By delving into the electronic response of the target on an attosecond timescale, the research sheds light on the chemical reactions induced by radiation, a crucial aspect that was previously only observable on a much slower picosecond timescale.
The research, led by a collaborative group of scientists from various Department of Energy national laboratories and universities in the U.S. and Germany, represents a pivotal step towards comprehending complex radiation-induced chemistry. The team’s ability to operate on the timescales where the action unfolds holds the promise of deepening the understanding of the effects of prolonged exposure to ionizing radiation on the chemicals present in nuclear waste.
Notably, the study’s significance extends beyond the realm of fundamental research, as it carries implications for practical applications such as the management of nuclear waste. The researchers’ efforts were bolstered by the participation of early-career network members, who later joined the full experimental and theoretical teams, underscoring the collaborative nature of this groundbreaking achievement.
This milestone marks a significant leap forward in the field of quantum physics, paving the way for a more comprehensive understanding of the intricate interplay between radiation and matter. As the scientific community continues to unravel the mysteries of the subatomic world, the implications of this pioneering research are poised to reverberate across various scientific disciplines, from nanotechnology to medicine, offering new avenues for exploration and discovery.
