论文摘要
双魔法$^{48} $ ca的等效巨型单极共振（ISGMR）的属性在基于Skyrme型相互作用的微观模型的框架中分析。已经开发了一种同时考虑到波功能中$ 0^{+} $状态中单，两和三个词之间的耦合的方法。包含三个音波配置会导致ISGMR强度重新分布，以降低能量$ 0^{+} $状态和更高的能量尾巴。我们的结果表明，开发的方法使我们能够描述ISGMR扩展宽度的总结构。
The properties of the isoscalar giant monopole resonance (ISGMR) for the double magic $^{48}$Ca are analyzed in the framework of a microscopic model based on Skyrme-type interactions. A method for simultaneously taking into account the coupling between one-, two-, and three-phonon terms in the wave functions of $0^{+}$ states has been developed. The inclusion of three-phonon configurations leads to a substantial redistribution of the ISGMR strength to lower energy $0^{+}$ states and also higher energy tail. Our results demonstrate that the developed approach enables to us to describe a gross structure of the ISGMR spreading width.
