The state |j,mi is an eigenstate of L 3 with eigenvalue m, L 3 |j,mi = m|j,mi because each application of L− lowers the eigenvalue of L 3 by one2. The normalization factors can be found by observing that

LECTURE 13 Maxwell–Boltzmann, Fermi, and Bose Statistics

This is called the “Maxwell–Boltzmann distribution.” It is the same as our previous result when we applied the canonical distribution to N independent single particles in a classical system. The sum over r is a sum over single particle states. Alternative Derivation of Maxwell–Boltzmann Partition Function We can write the

Comparison between Maxwell- Boltzmann, Bose-Einstein …

Maxwell Boltzmann statistics is applicable to identical, distinguishable particle of any type spin. The molecules of gas are particle of this type. Bose Einstein statistics is applicable to the identical, indistinguishable particles of zero or integral spin. These particles are called Bosons. Example photons, Helium atom.
