Southwest Research Institute (SwRI) scientists believe they may have resolved a 39-year-old mystery about the radiation belts ...

(Nanowerk News) One of the most fundamental interactions in physics is that of electrons and light. In an experiment at Goethe University Frankfurt, scientists have now managed to observe what is ...

Photoelectrons excited by extreme ultraviolet or x-ray photons in the presence of a strong laser field generally suffer a spread of their energies due to the absorption and emission of laser photons.

In a breakthrough discovery, scientists have unveiled a novel method for X-ray generation, offering enhanced flexibility in emitting X-rays in various directions or focusing them. A nurse checks the ...

Four years ago the first modern electron microscope was exhibited by the Siemens & Halske A.-G., in Berlin (TIME, June 6, 1938). Two years ago the R.C.A. Laboratories completed the first commercial ...
