With a wavelength of less than 100 nm, this intense UV radiation is essential for altering the electron states in helium ...

In this nonlinear process, both electrons simultaneously absorb two extreme-ultraviolet photons and ... and then sorted them according to the photon energy with the highest intensity (peak ...

it emits a photon with a particular wavelength in the ultraviolet spectrum, called a Lyman-alpha emission. A powerful energy source is required to energize hydrogen enough to produce the Lyman ...

The present review covers effects of moderate intensities of ultraviolet and infrared radiation ... matter has the capacity to store incident photon energy by resonance absorption.

And as an added bonus, reducing the amount of UV radiation that hits the solar cell ... The resulting films boasted blue to red photon conversion efficiencies as high as 95 percent.

The photon has fueled centuries of discovery ... Scientists collect strong signals, in the form of ultraviolet radiation, X-rays, and gamma rays emitted by energetic objects from our galaxy and beyond ...

The average person’s experience with an ultraviolet (UV ... systems are doing that he isn’t. [Mile’s] Photon wand tries to be energy efficient with more irradiated power while staying ...

If our photon were a gamma ray, an x-ray, or an ultraviolet ray, it would be absorbed or reflected by the upper atmosphere, and it would never reach the ground. The Sun emits radiation almost all ...

However, as the energy of the X-rays increases, the interaction with the crystals becomes smaller, making the measurements challenging. In this high-photon energy regime, a large proportion of the ...
