Which mechanism allows alpha particles to escape the nucleus during radioactive decay within heavy atom isotopes?

💡 Explanation

Alpha decay occurs when the alpha particle tunnels through the potential barrier, despite insufficient energy because there's a finite probability of penetrating the barrier according to quantum mechanics. Therefore quantum tunneling enables escape, rather than emission, repulsion or fission which depend on additional mechanisms or external factors.
