How a change in the movement of an electron changes the scattering of light, in a new experiment, measured more than 500 photons scattered from a single electron. Previous laser pointer experiments only scattered a few photons at a time. Image courtesy of Aurora Labs | University of Nebraska Lincoln. The unique nature of this X-ray can be applied in a variety of ways. Its extremely narrow range of energy and very short duration can help produce three-dimensional images on the nanoscale, while reducing the dose required to produce them.
This phenomenon is partly due to changes in electrons. It abandons the usual up and down movements and moves in an “8” pattern. Just as under normal conditions, electrons also eject their own photons, excited by the energy of the incident photons. But the researchers found that the ejected photons absorbed the collective energy of all scattered photons, emitting X-ray energy and wavelength.
These qualities enable it to find tumors or circumvent micro-cracks in conventional X-rays, map the molecular landscape of nanomaterials to semiconductor technology, or detect increasingly complex threats at security checkpoints. Atomic and molecular physicists can also use X-rays as ultrafast cameras to capture snapshots of electron movement or chemical reactions.
As a physicist, his colleagues are also excited about the scientific meaning of their experiments. By establishing the relationship between the brightness of the laser and its scattered light properties, the team confirmed the recently proposed method for measuring the peak intensity of the green laser pointer. The study also supports some long-term assumptions that physicists cannot directly test because of technical limitations. “Over the years, many theories have never been tested in the laboratory because we have never had a light source that is bright enough to experiment. We have confirmed various predictions about what will happen, and we have confirmed some of them.” “This It is part of what we call electrodynamics. All physicists have textbooks on classic electrodynamics. In a sense, this is a real textbook experiment. “
