Prediciting Bose Einstein statistics

SUMMARY

This discussion focuses on deriving predictions for Helium-4 (He-4) atoms at very low temperatures using the Maxwell-Boltzmann (MB) distribution. The key equation presented is the ratio of occupation numbers between the ground state and the first excited state, expressed as exp(ε1/kT), where ε1 is the energy of the first excited state and k is the Boltzmann constant. The discussion emphasizes the need to correctly apply Bose-Einstein statistics to predict the behavior of He-4 in a condensed state.

Homework Statement



First, let's derive the predictions for He-4 atoms at very low temps given the MB distr.


Homework Equations




The Attempt at a Solution



Given the MB distr., if the ground state of the system is assumed to be at zero energy, then the ratio of occupation numbers between the ground and the first excites states is exp([tex]\epsilon<sub>1</sub>[/tex]/kT).

What do you guys think? Have I done all right so far?
