论文摘要
基于Hartree-fock状态的变形壳模型（DSM）的框架，计算出$^{23} $ Na的弱相互作用巨大颗粒（WIMP）的弹性和非弹性散射的检测率。首先，计算诸如能能光谱和磁矩之类的光谱特性，并与实验进行比较。遵循这些良好的一致性，DSM波函数用于获得WIMP-$^{23} $ na散射的弹性和非弹性自旋结构，核结构系数等。然后，还使用给定的一组超对称参数计算事件速率。还以相同的方式使用DSM波函数，还获得了从$^{40} $ ar的WIMP弹性散射的核结构系数和事件速率。这些事件率以及年度调制的结果对于即将到来的和未来的WIMP检测实验，涉及$^{23} $ Na和$^{40} $ ar的检测器。
Detection rates for the elastic and inelastic scattering of weakly interacting massive particles (WIMP) off $^{23}$Na are calculated within the framework of Deformed Shell Model (DSM) based on Hartree-Fock states. First the spectroscopic properties like energy spectra and magnetic moments are calculated and compared with experiment. Following the good agreement for these, DSM wave functions are used for obtaining elastic and inelastic spin structure functions, nuclear structure coefficients etc. for the WIMP-$^{23}$Na scattering. Then, the event rates are also calculated with a given set of supersymmetric parameters. In the same manner, using DSM wavefunctions, nuclear structure coefficients and event rates for elastic scattering of WIMP from $^{40}$Ar are also obtained. These results for event rates and also for annual modulation will be useful for the upcoming and future WIMP detection experiments involving detectors with $^{23}$Na and $^{40}$Ar.
