All descendants ought to set form_type
to indicate whether the mass formula is discrete or continuous
The binding energy is defined
where is the mass of the nucleus including the mass of the electrons. The mass excess is defined
For example, for , the binding energy is 1801.695 MeV, the mass excess is 47.30366 MeV, and
is 221742.9 MeV. This is consistent with the above, as
is 938.7830 MeV,
is 939.5650 MeV, and
is 931.494 MeV.
Some common reaction Q-values and separation energies:
: Beta-decay energy
: Double beta-decay energy
: Four beta-decay energy
: Alpha-decay energy
: Beta-delayed neutron emission decay energy
:

: Electron capture decay energy
: Electron capture with delayed proton emission decay energy
:

: Neutron separation energy
: Proton separation energy
: Two neutron separation energy

int get_nucleus | ( | int | Z, | |
int | N, | |||
nucleus & | n | |||
) | [inline] |
Fill n
with the information from nucleus with the given neutron and proton number.
All masses are given in . The total mass (withouth the electrons) is put in part::m, and the degeneracy (part::g) is arbitrarily set to 1 for even A nuclei and 2 for odd A nuclei.

virtual double binding_energy | ( | int | Z, | |
int | N | |||
) | [inline, virtual] |
Return the binding energy in MeV.
The binding energy is defined to be negative for bound nuclei, thus the binding energy per baryon of Pb-208 is about -8*208 = -1664 MeV.

virtual double binding_energy_d | ( | double | Z, | |
double | N | |||
) | [inline, virtual] |
Return the binding energy in MeV.
The binding energy is defined to be negative for bound nuclei, thus the binding energy per baryon of Pb-208 is about -8*208 = -1664 MeV.
