[題目]
the energy level of a localized oscillator is given by ε=(n +1/2)hυ,
with n= 0,1,2,3... Consider a system consisting of N such weakly interacting
oscillator which has the total energy U=1/2 Nhυ+1/2 Mhυ, where M is an
integer.
(a)Find the multiplicity Ω(M)
(b)Find the temperature T of the system as a function of N and M(or N and U),
under thee condition N>>1 and M >>1.
(c)Find U as a function of T, i.e.,U=U(T)

[瓶頸]

完全不知道要如何找Ω,M應該是N個不一定相同的n的和,但我不知道有幾種n啊
怎麼計算呢?

請高手相助
小弟一拜
