← ScienceIf Uranium-235's nucleus is close to fission, which mechanism increases if neutron binding energy input exceeds threshold for separation?
A)Reduced alpha decay probability
B)Increased spontaneous fission rate✓
C)Enhanced neutron capture stability
D)Increased beta decay emission frequency
💡 Explanation
Fission increases because neutron absorption surpasses the critical energy needed to overcome the nuclear strong force during nuclear binding; therefore, the nucleus splits apart from neutron bombardment, rather than maintaining stability via weaker forms of radioactive decay.
