Prob. 16. A hypothetical system contains two different particles, each of which is capable of having the energies e: 0, 1, 4, 9,..., i^2,..., (x0).
Assume that there is no interaction energy between the particles so that the total energy of the system is E = e1 + e2.
(a) Some of the values of Wi, the number of degeneracy of energy level l, are listed in the table. Complete this table.

(b) Determine the values of e - Ei in (a), if e0 = 1.
(c) Determine the partition function for a canonical ensemble, making the assumption that only five energy levels l = 0, 1, 2, 3, 4 are needed, and the contribution from higher energy levels can be ignored.
(d) What is E?
