(PhysOrg.com) -- Double-core-hole (DCH) states – in which two electrons are ejected from their positions, creating vacancies – occurring at different atomic sites are very sensitive to the chemical environment of ...
A study of electron dynamics timed to millionths of a billionth of a second reveals the damage radiation can do on a molecular level.
