← ScienceWhich outcome results when nuclear binding energy decreases within fissile isotopes?
A)Higher probability of spontaneous fission✓
B)Increased likelihood of beta decay
C)Elevated threshold for induced fission
D)Greater neutron capture cross-section impact
💡 Explanation
Decreased nuclear binding energy weakens the forces holding the nucleus together, leading to a higher probability of spontaneous fission because the nucleus is less stable; therefore, spontaneous fission increases rather than beta decay or requiring higher energy thresholds.
