Which outcome results when an unstable isotope undergoes alpha decay?

A)Nuclear binding energy redistribution.
B)Increased rate of nuclear fission.
C)Neutron absorption cross-section declines.
D)Electron degeneracy pressure increases greatly.

💡 Explanation

Alpha decay from unstable isotopes leads to nuclear binding energy redistribution because heavy nuclei become more stable by lowering the repulsive forces via quantum tunneling of the alpha particle; therefore lower energy follows rather than fission or neutron absorption under normal decay.
