Inheritance diagram for o2scl::nucmass_dz_fit:
Detailed Description
This class is designed to provide essentially identical results to the original 10-parameter Duflo-Zuker code (see Duflo95) at
http://amdc.in2p3.fr/theory/du_zu_10.feb96fort
The default values of nucmass::m_neut and nucmass::m_prot are adjusted to make sure that the mass excesses match the values given in the original.
- Idea for Future:
- This appears to be limited for large nuclei because 'i' becomes larger than imax and then statements like noc[i][j]=moc-ju and noc[i+1][j]=ju become invalid. This needs to be more carefully understood and documented. For now, is_included() just arbitrarily chooses 240 as a maximum for N and Z.
- Todo:
- Document each field.

Member Function Documentation
◆ binding_energy()
|
virtual |
This function reproduces the original function called mass10(), except that, to be consistent with the other O2scl nuclear mass classes, it returns the binding energy with the opposite sign from the original.
Reimplemented from o2scl::nucmass.
