Abstract: We have established the excitation energy spectrum of He II by including the Hartree term. We compare then the excitation energy spectrum thus obtained to experimental spectra. We can obtain approximately the temperature dependence density relation of the quasi particle and we see that the behavior of Cv, the specific heat, versus T, the temperature, can be reproduced for all T ≤ 2.1 K.
