Fano resonances in nanoscale structures
... level, which can spontaneously ionize by ejecting an
electron into the continuum, A + ប → A* → A+ + e. Such
levels were said to be autoionizing, after Jevons and
Shenstone 共1938兲. In other words, the autoionized state
is a bound state of an atom with energy above the first
ionizing threshold. Autoi ...
