For that matter, what does it even mean to talk ... we see some combination of the "bare" electron and its interaction with the rest of the universe. These interactions change the energy of ...

An inner electron in a low energy level can rise to a higher energy level. We say that it becomes ‘excited’. An electron can be excited when its absorbs energy from electromagnetic radiation.

The majority of our evidence for dark matter’s existence comes from observing visible (or baryonic) matter that does not exert enough gravitational force to explain why, say, an object is orbiting ...

Atomic and molecular interactions with ... is associated with an electron moving from one energy level to another. The time crystal is an exotic phase of matter where time-translational symmetry ...

This means that their resulting interaction with matter (i.e. groupings of atoms ... boosting the energy state of its electron(s) before possibly being re-emitted as the excited electrons decay ...

The technique leverages the interaction of electrons with matter to provide insights into the crystal structure, phase, orientation, and electronic properties of materials. The process begins with ...

Our estimates of the size of a neutrino span from smaller than an atomic nucleus to as large as a few metres, but now we are ...

It provides insights into X-ray multiphoton ionization and its impact on electron behavior. The findings enhance understanding of XFEL interactions with matter, particularly the interplay between ...

"There is no reason to believe that dark matter will interact with regular matter in ... and those associated with a particle knocking an electron off a xenon atom. The difference between these ...
