Packing fraction

  1. Feb 28, 2006 #1
    Can anybody help me to get packing fraction of H mass 2 equal to 2.01402u?

    If you add the individual rest mass of a neutron & of a proton (i'm assuming you're asking about the nuclide, not the whole atom of deuterium) what do you get...? Can you estimate the bond energy...?

    What is meant by packing fraction? There are only two nucleons, the proton and neutron, in the deuteron, or nucleus of the deuterium atom.

    Are you asking about binding energy as dextercioby mentioned?

    I mean packing fraction = -BE/A which related how tightly bound/particle the system is.
    Is approximately -8 MeV / nucleon for most nuclides.
