Abstract：
Within the framework of Hartree-Fock theory with extended Skyrme effective interaction, the excitation energy as a function of temperature and density was investigated and used to analyse the ALADIN calaric curve. Our work began on the assumption that the temperature plateau of ALADIN calaric curve was resulted from the compression excitation energy. The theoretical calculations with this assumption were in good agreement with the ALADIN caloric curve, which indicates that our assumption is reasonable, i.e., the temperature plateau of ALADIN calaric curve is resulted from the compression excitation energy, and liquid-gas phase transition isn’t the only interpretation for the ALADIN caloric curve. Therefore, we provided a new interpretation for the ALADIN caloric curve.
