  • lõhustumine - aatomituuma muundumine kaheks (harvemini enamaks) ligikaudu võrdse massiga kildtuumaks. Raske tuuma lõhustumisel vabaneb energiat ja kiirgub mitu neutronit, mis võivad tekitada ahelreaktsiooni. Lõhustumine võib toimuda neutronite, prootonite, footonite jt osakeste mõjul või spontaanselt.
