Study of static and thermal properties of symmetric and asymmetric nuclear matter using generalized density-dependent M3Y interaction

Abstract

By using the most recent generalized form of the density-dependent nucleon-nucleon DDM3Y interaction, namely, CDM3Yn-Paris interaction, the basic static properties of symmetric and asymmetric nuclear matter such as binding energy per particle, pressure, velocity of sound, and compressibility are calculated. Also, at finite temperature, the thermal properties of nuclear matter are studied, such as the free energy, the pressure, the entropy, and the compressibility. In addition, a comparison using different density-dependent M3Y-Paris interaction (DDM3Y1 and BDM3Y1) is considered. The importance of using the density-dependent term in the M3Y-Paris interaction is to fulfill the saturation requirement for the nuclear matter because M3Y-Paris interaction has an attractive character. Thus, the nuclear matter generated with this interaction is unstable against collapse. This new version of the DDM3Y is the general one, and other previous density-dependent forms can be considered as a special case of this one. Therefore, all the explicit theoretical developments are based on the density-dependent CDM3Yn version. The results obtained are in good agreement with previous theoretical estimates.
