论文摘要
在等素对称性和不对称核物质中,我们研究了与零声音激发有关的结构函数。在具有Landau-Migdal准粒子相互作用的简单模型中,核物质的密度响应$π^r(ω,k)$ to to n ocutation $ v_0(ω,k)$。 In the previous papers the complex branches of solutions $ω_{si}(k)$, $i=n,p,np$ of the dispersion equation corresponding to zero sound excitations in the symmetric and asymmetric nuclear matter are obtained.现在,我们根据这些解决方案研究了核问题的结构和响应功能。
In isospin symmetric and asymmetric nuclear matter we study the structure functions connected with the zero sound excitations. In the simple model with Landau-Migdal quasiparticle interactions the density response $Π^R(ω,k)$ of the nuclear matter to the small isovector external field $V_0(ω,k)$ is considered. In the previous papers the complex branches of solutions $ω_{si}(k)$, $i=n,p,np$ of the dispersion equation corresponding to zero sound excitations in the symmetric and asymmetric nuclear matter are obtained. Now we investigate the structure and response functions of nuclear matter based on these solutions.
