← ScienceWhich mechanism allows beta particles to escape nuclei?
A)Quantum tunneling through potential barrier✓
B)Classical scattering surpasses binding energy
C)Photoelectric emission exceeds work function
D)Thermionic emission lowers activation energy
💡 Explanation
Quantum tunneling permits electrons to escape the nucleus even when they lack the classical energy to overcome the potential barrier, because the electron wave function has a non-zero amplitude outside; therefore tunneling occurs, rather than classical emission that requires surpassing an energy threshold.
