Which effect allows alpha decay in heavy nuclei?

💡 Explanation

Quantum tunneling allows alpha particles to escape the nucleus, because there is a probability the particle will tunnel through the potential barrier, therefore decay occurs, rather than remaining trapped, because the potential barrier is finite.
