Quantum Mechanics uncertianty in momentum

  1. Aug 17, 2009 #1
    1. The problem statement, all variables and given/known data

    A neutron star has a core composed of protons and neutrons (nucleons) and has a density
    higher than the nuclear saturation density ns = 0.16 fm ^−3
    .
    (i) [6 points] Assuming nuclear saturation density throughout the core, calculate the
    uncertainty in momentum for a nucleon in the core.




    2. Relevant equations



    3. The attempt at a solution

    (i) I have no idea how to go about this at all none of the equations I know deal with a density

    From the density of the core, you can work out how much space each nucleon occupies and hence the uncertainty in the position of a nucleon.
