Multi-electron process in which two or more electrons are emitted, partitioning between them the excess kinetic energy.
Note: Shakeoff leads to a continuum background intensity at kinetic energies below that of the parent peak in the electron spectrum. This is in contrast to
shakeup, which leads to peak structure, also at kinetic energies below that of a parent peak.
