Symmetry energy

  1. Nov 13, 2008 #1

    Can someone please explain me what is the symmetry energy?
    I know asymmetry energy in the weizsacker semiempirical mass formula which is the gap between a nucleus and it's isobar with Z=N.

    Symmetry and asymmetry energy are the same things. There is some confusion on name in literature. Mostly in literature the symmetry energy is reffered to the (N-Z)^2/A term in the weizsacker semiempirical mass formula. But it is also reffered as the asymmetry energy.
