相对论平均场论中复动量表象与格林函数方法的结合

Combination of complex momentum representation and Green's function methods in relativistic mean-field theory

Min Shi, Zhong-Ming Niu, Haozhao Liang

摘要:

在相对论平均场框架下,我们将复动量表象方法与格林函数方法相结合,建立了RMF-CMR-GF方法。用这种新方法研究了$^{74}$ Ca的晕结构。在不引入任何非物理参数的情况下,精确地计算了所有共振态的连续谱能级密度,且与积分围线的选择无关。详细讨论了$^{74}$ Ca中晕现象的重要单粒子波函数和密度。

英文摘要:

We have combined the complex momentum representation method with the Green's function method in the relativistic mean-field framework to establish the RMF-CMR-GF approach. This new approach is applied to study the halo structure of $^{74}$Ca. All the continuum level density of concerned resonant states are calculated accurately without introducing any unphysical parameters, and they are independent of the choice of integral contour. The important single-particle wave functions and densities for the halo phenomenon in $^{74}$Ca are discussed in detail.
