Problem
A separate density fit for another nucleus gives a central nucleon density ρ0=0.155fm−3. Using the free Fermi-gas model (nucleon rest mass energy mc2=939MeV), find
((a)) the Fermi energy ϵF,
((b)) the kinetic part of the asymmetry-energy coefficient, ϵF/3,
((c)) the fraction of the fitted liquid-drop value aA=23MeV that this kinetic term alone accounts for.
