Differential number of particles in Fermi gas model

[QUOTE="Ross Greer, post: 5434913, member: 590208"] I'm practicing for the Physics GRE, and came across a question that has me stumped. "In elementary nuclear physics, we learn about the Fermi gas model of the nucleus. The Fermi energy for normal nuclear density (ρ[SUB]0[/SUB]) is 38.4 MeV. Suppose that the nucleus is compressed, for example in a heavy ion collision. What is the dependence of Fermi energy on density?" I took a peek at the solution, but I've forgotten where I would have seen the first step: "The differential number of particles is dN = 4V/(2π)[SUP]3[/SUP] d[SUP]3[/SUP]K, where g = 4 is the nuclear degeneracy." Where does this equation come from? Are there any books or online readings you could recommend to better learn this material? I would be able to finish the problem if I could recall the first step. (For those curious, the solution was ρ[SUP]2/3[/SUP] Side note: If anyone has any Physics GRE prep materials they would recommend, I'd greatly appreciate it! Thanks for your help! [/QUOTE]
