摘要
本文运用有限温度实时格林函数方法,在正常配对和反常配对切断近似下,推导了具有Gogny D1有效势核物质的状态方程和能隙方程.得出液汽相交临界温度和超导相交的临界温度分别是14.8MeV和0.2MeV.能隙只取决于Gogny势中有限力程部分.
The finite temperature real time Green's function method with normal pair cutoff and abnormal pair cutoff approximation is applied to derive the equation of state and the energy gap equation for nuclear matter with the Gogny D1 effective interaction. The critical temperature for liquid-gas phase transition and for superconducting phase transition are found to be 14.8 MeV and 0.2 MeV respectively. The energy gap is determined by the finite range part of the Gogny D1 interaction only.
