Observation of electron emission in the nuclear reaction between protons and deuterons

Physics Letters B, 2017
Proton–deuteron fusion reaction has been studied using a proton beam with an energy of 260 keV and a deuterium-implanted graphite target. The reaction product, 3He, usually de-excites by γ-ray emission.

Whispering gallery and surface mode of electrons in lateral and corrugated quantum dots

Materials Research Express, 2020
Quantum dots (QDs) are fundamental elements in the applications related to light–matter interaction, such as solar cells, lasers and sensors. Moreover, some modes of electrons including whispering galley modes (WGMs) and surface modes can be incorporated

Intense laser interaction with micro-bars

Scientific Reports, 2023
Intense laser fields interact very differently with micrometric rough surfaces than with flat objects. The interaction features high laser energy absorption and increased emission of MeV electrons, ions, and of hard x-rays.

Very High-Energy Electron Therapy Toward Clinical Implementation

Cancers
The use of very high energy electron (VHEE) beams, with energies between 50 and 400 MeV, has drawn considerable interest in radiotherapy due to their deep tissue penetration, sharp beam edges, and low sensitivity to tissue density. VHEE beams can be precisely steered with magnetic components, positioning VHEE therapy as a cost-effective option between ...

Evidence for shock acceleration of high-energy electrons in the supernova remnant SN1006

Nature, 1995
HIGH-ENERGY cosmic rays (relativistic heavy nuclei) play an important role in heating interstellar matter in the Milky Way1,2, and they affect chemical abundances through collisions with atoms in the interstellar gas2.
