Fix the kinetic energy symmetry coefficient from the nucleon effective mass and the saturation density.
This assumes the nucleons are non-relativistic and that the neutrons and protons have equal mass. The relativistic corrections are around 1 part in .

virtual double eoa_zeroden | ( | ) | [inline, virtual] |
Return the energy per baryon of matter at zero density.
This is inaccessible from calc_e() so is available separately here. Using set_kprime_zeroden() or set_kpp_zeroden() will fix kprime or kpp (respectively) to ensure that this is zero.
The result provided here does not include the nucleon mass and is given in .

The kinetic energy symmetry coefficient in MeV (default 17).
The default value corresponds to an effective mass of about 0.7.
