1. 2.19×10⁷ and 5.92×10⁵.
2. Si: 0; P: 3µ_B (max component) or sqrt(15)µ_B (abs.value); S: 3µ_B (max component) or sqrt(27/2)µ_B (abs.value);
3. call x=ε/k_BT; Z=1/(1-exp(-x)); u=ε/(exp(x)-1); C_V^mol=R x² exp(x)/(exp(x)-1)²; a grande T: R(1-x); a piccola T: R x²exp(-x)
4. λ=1.78 meV
5. C_V^mol= R 3.586×10^-6 (T/K)³ = 2.982×10^-5(T/K)³
