Chapter 37, Problem 63P

(a) Count the number of electron states N(E) with energy equal to or less than E in Equation 35.8 by finding the volume available to such states in the space with Cartesian coordinate axes nx, ny, nz. (Hint: Consider each set of positive integers, at the corner of a unit cube, and that lies inside a radius n x 2 + n y 2 + n z 2 , and remember that there are two spin values per state.) (b) Differentiate N(E) with respect to E to obtain Equation 37.5.

The expression for the Fermi energy of electrons in a stellar interior is εF =ℏ2 /2me   [3pi 2   Z/A  ρ/mp  ] 2/3   (See image) Derive the condition on the temperature and density for the electrons in the stellar interior to bedegenerate. Briefly explain the reason for this limit. Demonstrate that the condition for degeneracy you have found corresponds to a straight line ina plot of log T versus log ρ. Use the condition you have found to calculate whether the centre of the white dwarf Sirius B isdegenerate. Use values of ρc = 3.0 × 109 kg m−3,  Tc = 7.6 × 107 K,  and Z/A = 0.5.
