(Courtesy: Sabrina Hopp/Angelika Stehle) The interaction between an electron and a calcium-40 nucleus has been calculated from first principles for the first time. Physicists in Germany and the US led ...

Our combination of HRTEM experiments and first-principles electronic structure calculations opens a new way to investigate electronic configurations of point defects, other non-periodic ...

AES operates on the principle of the Auger effect ... This creates vacancies, leading to a cascade of electron transitions within the atom as electrons from higher energy levels drop down to fill the ...
