However, with wavelengths of only 13 nanometers and high radiation intensities of several petawatt per square centimeter something else – at least with some atoms – happens: With xenon, a whole ...

Megavoltage radiation beams are nowadays widely used for anticancer radiotherapy. High-energy linear accelerators allow highly penetrating radiation to treat targeted volumes with a better sparing of ...

WHEN a beam of X-rays passes through a medium, three kinds of phenomena may be observed: the photoelectric effect, the Compton effect, and the socalled classical scattering. The conversion of the ...

FRANKFURT. It is now exactly one hundred years ago that Albert Einstein was awarded the Nobel Prize in Physics for his work on the photoelectric effect. The jury had not yet really understood his ...

June 9, 2022, marks 117 years since Einstein published his groundbreaking paper on the photoelectric principle. The analysis was published on June 9, 1905, also known as Einstein’s “miracle year” ...

Almost a hundred years ago, Albert Einstein won a Nobel Prize for his research on the phenomenon. The photoelectric effect is the emission of electrons when electromagnetic radiation, such as light, ...

The photoelectric effect is the emission of electrons from matter upon the absorption of electromagnetic radiation, such as ultraviolet radiation or x-rays. Upon exposing a metallic surface to ...
