Marta Borrajo, Tomás R. Rodríguez, J. Luis Egido

摘要:

首次用时间反演对称性破缺Hartree-Fock-Bogoliubov(HFB)态和Gogny D1 S相互作用的对称性守恒组态混合方法(SCCM)进行了计算.该方法包括粒子数和三维角动量对称性简化以及组态混合内的生成坐标方法(GCM)的框架。选择核$^{32}$ Mg来显示计算的性能和可靠性。此外,$0^{+}_{1}$,$2^{+}_{1}$和$4^{+}_{1}$状态计算的镁同位素链,其中一个显着的压缩的光谱是通过包括曲柄状态,导致一个非常好的协议与已知的实验数据。

英文摘要:

We present the first calculations of a symmetry conserving configuration mixing method (SCCM) using time-reversal symmetry breaking Hartree-Fock-Bogoliubov (HFB) states with the Gogny D1S interaction. The method includes particle number and tridimensional angular momentum symmetry restorations as well as configuration mixing within the generator coordinate method (GCM) framework. The nucleus $^{32}$Mg is chosen to show the performance and reliability of the calculations. Additionally, $0^{+}_{1}$, $2^{+}_{1}$ and $4^{+}_{1}$ states are computed for the magnesium isotopic chain, where a noticeable compression of the spectrum is obtained by including cranked states, leading to a very good agreement with the known experimental data.
