【 摘 要 】

Exchange interaction and correlations radically change behaviour of of a quantum particle in a classically forbidden region. Exchange produces a power-law decay instead of the usual exponential decrease of the wave function. Exchange-assisted tunneling enhances annihilation of positron with inner-shell electrons and produces other observable effects.
