When energy is added to uranium under pressure, it creates a shock wave, and even a tiny sample will be vaporized like a small explosion. By using smaller, controlled explosions, physicists can test on a microscale what could previously be tested only in larger, more dangerous experiments. In a recent experiment, scientists used a laser to ablate atomic uranium while recording chemical reactions as the plasma cooled, oxidized and formed species of more complex uranium. They discuss their work in this week’s Physics of Plasmas.
