AI总结:

本文在SUSY最小扩展框架下,利用BCS+QRPA及准粒子-声子耦合方法计算了WIMP与奇质量数Ge、Xe靶核弹性散射的核自旋含量,并与已有文献结果进行了比较。

摘要:

在SUSY模型最小扩展的框架下,分析了暗物质粒子(WIMP)与奇质量数$^{73}$Ge和$^{131}$Xe靶核的相互作用,即WIMP被这些原子核弹性散射所对应的反冲率。采用BCS+QRPA技术以及准粒子-声子耦合方案来描述计算中的核结构部分。将得到的两个原子核的核自旋含量值与文献中先前报道的值进行了比较。

英文摘要:

Abstract: The interaction of dark matter particles (WIMPs) with the odd-mass $^{73}$Ge and $^{131}$Xe target nuclei ,{ {that is the recoil rates corresponding to the elastic scattering of WIMPs by these nuclei}}, is analysed in the context of the minimal extensions of the SUSY model. The BCS+QRPA technique plus the quasiparticle-phonon coupling scheme is used to describe the nuclear structure part of the calculations. The resulting values for the nuclear spin content of both nuclei are compared to values previously reported in the literature.
