Problem 7.17. An ideal Bose-Einstein gas consists of noninteracting bosons of mass m which have an internal degree of freedom which can be described by assuming, that the bosons are two-level atoms. Bosons in the ground state have energy Eo = p/2m, while bosons in the excited state have energy E = p/2m+A, where p is the momentum and A is the excitation energy. Assume that AkBT. Compute the Bose-Einstein condensation temperature, Te, for this gas of two-level bosons. Does the existence of the internal degree of freedom raise or lower the condensation temperature?
