Webr0 = σ* (2^ (1/6)) ≈ 1.122σ Therefore, the equilibrium interatomic spacing is approximately 1.122 times the atomic radius σ. (b) To find the bond energy, we substitute the equilibrium interatomic spacing r0 into the expression for E (r): E_b = 4ε [ (r0/σ)^12 - (r0/σ)^6] E_b = 4ε [ (1.122σ/σ)^12 - (1.122σ/σ)^6] View the full answer Final answer WebThe dense HED regime includes highly degenerate matter, with interatomic spacing less than the de Broglie wavelength.
