Which mechanism causes alpha particle emission within unstable, heavy nuclei?

💡 Explanation

Alpha decay occurs via quantum tunneling, where alpha particles penetrate the potential barrier despite insufficient energy because the wave function exhibits a finite probability inside allowed regions; therefore tunneling allows escape rather than classical over-barrier decay.
