2. For each of the partition functions given below, find the 6 lowest energies in the spectrum of the corresponding system, together with their multiplicities (degeneracies). You can organize those in a table as follows: CT (a) e-BE Z = 1 - e-2BE (1 + 2e-0.7BE + 3e-1.3BE) 2 (b) 1 Z = (1 - e-2BE)2 (ev. raBE + 5e-1.25BE) (c) Z = (1+ 2e-0.6BE + 3e-0.8Be) (1 + e-1.2BE + 4e-1.6Be) (BE + 1) 2 (d) 1 Z = BE 1 - e-2BE 1 - 3e-BE
