Which constraint drastically increases when barrier width decreases in quantum tunneling?

A)Radioactive decay half-life shortness
B)Electron’s potential momentum stability
C)Superconductor's critical temperature stability
D)Metallic bond's structural binding strength

💡 Explanation

Radioactive decay half-life decreases significantly as a result from the quantum tunneling increase; because barrier penetration becomes more probable via wave function transmission. Radioactive decay rate is therefore accelerated, rather than potential momentum being affected in the atoms.
