Fermi Temperature

  1. Feb 11, 2007 #1
    1. The problem statement, all variables and given/known data

    Calculate T(fermi), the fermi temperature for

    a) Liquid 3He (density 81kg/m^3) [these are not electrons]
    b) neutrons in a neutron star (density 10^17 kg/m^3)

    2. Relevant equations

    n, number density = z*Na*p / M (Na=avogadro, z=valence,p=density,M=molecular mass)

    Kf^3 = 3pi^2 * n (Kf = fermi radius)

    Ef = hbar^2 * Kf^2 / 2*m (fermi energy)

    Tf = Ef/Kb (Kb - boltzmann)

    3. The attempt at a solution

    Only ever done these where we're dealing with electrons (for ex, potassium etc). Not sure where to go with it...
