An atom’s nucleus is a collection of fermions— protons and neutrons.
(a) In calculating the Fermi energy in a nucleus, the protons and neutrons must be considered separately. Why?
(b) Find the Fermi energy of (i) the protons and (ii) the neutrons in a uranium nucleus, which has a radius of 7.4 x 10-15 m and contains 92 protons and 146 neutrons.
[#168] Such stuff as dreams are made of.
How much of you is not vacuum? Outside of the nucleus, an atom contains mostly empty space. Estimate the fraction of the volume of an atom that is occupied by the nucleus. Assume that a typical atom has a linear dimension of about 0.1 nm and that a typical nuclear dimension is about 1 fm. (Note that this problem introduces some new prefixes: n is nano or 10^{-9}10−9, p is pico or 10^{-12}10−12, f is femto or 10^{-15}10−15).
Give your answer as a power of ten. For example, enter: 10^18, or 10^-3 (for 10^{18}1018 or 10^{-3}10−3).
.In sodium there are about 2.6 x 1028 conduction electrons per cubic metre
which behave as a free electron gas. Fronm these facts estimate the Fermi
energy of the gas and an approximate value of the molar electronic heat
capacity at 300K.

- Stars similar to our sun eventually become white dwarfs, in which the hydrogen and helium have fused to form carbon and oxygen. The star has collapsed to a much smaller radius, which is why it is described as a “dwarf.” The electrons are not bound to the nuclei and form a degenerate Fermi gas within the white dwarf. Consider a white dwarf with a mass equal to the sun’s mass (1.99 x 1030 kg) but a radius of only 6.96 x 106 m, which is just 1% of the sun’s present radius.
