As an elementary type of collective excitation, plasmon has been found to dominate the optical properties of metals. The collective behavior of electrons in plasmons reflects the important difference ...

Laser-assisted electron scattering was observed using circularly polarized femtosecond laser pulses in the near-infrared range, a first for this technique. Energy and angular distributions of ...

LAES measurement using circularly polarized light. A femtosecond laser pulse and an electron pulse were fired at an argon gas beam at the same time, giving a scattering signal whose energy and angular ...

What is Electron Energy Loss Spectroscopy? Electron energy loss spectroscopy (EELS) is a powerful analytical technique used to study the chemical composition, electronic structure, and local bonding ...

The high-energy radiation that carries orbit angular momentum has become an extremely important tool to investigate the angular momentum-related physics in the microworld. But the generation and ...
