← ScienceWhich outcome results when insufficient cohesive energy increases?
A)Material undergoes spontaneous alpha decay
B)Nuclear binding energy decreases drastically
C)Spallation fragments increase dramatically✓
D)Internal beta decay transitions increase
💡 Explanation
Insufficient cohesive energy results in spallation because incident particles transfer lots momentum during impact, decreasing the effective binding between nucleons. Therefore, fragment yields rise sharply on disintegration, rather than exhibiting alpha (or beta) decay modes that require quantized energy.
