## Particle Mass references

Following is the table of particle mass references.

These values are based on PDB and G.Audi et al. / Nuclear Physics A 729 (2003) 337–676. Please use these values for your analysis or simulation code.

Calculation formula is following:

<math>M_{nucl}=M_{atom}-M_{e}{\cdot}Z+B_e</math>

<math>M_{atom}</math> is given in the table of Audi's paper.

<math>B_e</math> is electron binding energy, which is also given in Audi's paper as follows;

<math>B_e=14.4381{\cdot}Z^{2.39}+1.55468{\times}10^{-6}{\cdot}Z^{5.35} eV</math>
