- Defined in File ParticleMass.h
Return the nucleus mass by lookup from a table. The masses are the atomic masses from the NIST database (http://www.nist.gov/pml/data/comp.cfm) minus electron masses, neglecting electron binding energies. Unmeasured atomic masses are taken to be A * amu minus electron masses. The data table is generated by data-tools/NuclearMass/createNuclearMassTable.
