1. Relationship between nuclear binding energy (B) and mass defect (D)
B (Z,A) = [Zm(1H) +Nmn – M(Z,A)]c2
D = [M(Z,A) – A]c2
all masses in atomic mass units (u)
 B + D = [Zm(1H) +Nmn – A]c2
= [Z( ) + N( ) – Z – N]c2
= [Z( ) + N( )]c2

2. Nuclear radii Nuclei have nearly constant density
A/(4/3)pR3 ~ constant
 R a A1/3
 R = R0 A1/3 , with R0 = 1.2 fm
