← ScienceWhich consequence results when nuclear binding energy defects exist in uranium?
A)Decreased probability of spontaneous fission
B)Increased neutron capture cross-section
C)Reduced stability against alpha decay✓
D)Enhanced isotopic enrichment performance
💡 Explanation
A binding energy defect reduces the energy required for the protons to overcome their combined electric repulsion, thus increasing the chance of alpha decay, because the nucleus is less energetically stable. Therefore, C, rather than fission initiation, because more energy required given spontaneous emission event constraints.
