Class nucmass_densmat (o2scl)¶
-
class nucmass_densmat¶
A nuclear mass formula for dense matter.
This class is experimental.
The default set of nuclear masses is from the AME 2012 mass evaluation and is automatically loaded in the constructor.
- Idea for Future:
If this isn’t going to be in a child of nucmass, then maybe we can simplify binding_energy_densmat_derivs() to just
binding_energy().
Public Functions
-
inline virtual const char *type()¶
Return the type,
"nucmass_densmat".
-
nucmass_densmat()¶
-
virtual void test_derivatives(double eps, double &t1, double &t2, double &t3, double &t4)¶
Test the derivatives for binding_energy_densmat_derivs()
-
virtual void binding_energy_densmat_derivs(double Z, double N, double npout, double nnout, double nneg, double T, double &E, double &dEdnp, double &dEdnn, double &dEdnneg, double &dEdT)¶
Compute the binding energy of a nucleus in dense matter and derivatives.
This function computes the binding energy of a nucleus in a sea of protons, neutrons, and negative charges (usually electrons) at a fixed temperature, relative to homogeneous nucleonic matter with the same number densities of protons, neutrons, and negative charges. The proton number Z and neutron number N should also be counted relative to homogeneous nucleonic matter, not relative to the vacuum.
As in o2scl::nucmass::binding_energy_d(), the binding energy returned in
Ehas units of MeV. All densities are expected to be in \( \mathrm{fm}^{-3} \), and the temperature should be in MeV.- Idea for Future:
Extend to negative N and Z?
-
virtual void binding_energy_densmat(double Z, double N, double npout, double nnout, double nneg, double T, double &E)¶
Compute the binding energy of a nucleus in dense matter without the derivatives.
