Nuclear Masses

• Nuclear masses are measured relative to the mass of 12C, which is defined to have a mass of 12.00000 amu.

  • 1 amu = 1 u = 931.5 MeV/c2

• Mass of proton = 1.007825 u = 938.27 MeV/c2

• Mass of neutron = 1.008665 u = 939.57 MeV/c2

• Mass of Hydrogen = 938.78 MeV/c2

• Mass of Nucleus ¹ Z(mp) + N(mn)
