本文介绍原子核的自旋-同位旋集体激发态,以及研究这些集体激发态的常用HF+RPA或HFB+QRPA理论模型.这些集体激发态的研究能够获得对自旋相关的核子-核子相互作用的信息和理解.自洽的Skymre HF+RPA模型被用于研究闭壳核的GT和SD(自旋偶极)跃迁,张量相互作用对这些跃迁的主峰能量有显著效应,这些效应对Skyrme张量相互作用的强度给出很强限制.对于N~Z的pf壳原子核,同位旋标量(IS)对相互作用对低能强GT态有决定性作用,通过某些特定核的低能强GT态的能量很好地限制IS对相互作用的强度.
In this paper, the spin-isospecific collective excited states of nuclei and the common HF + RPA or HFB + QRPA theoretical models for the study of these collective excited states are described. These collective excited states can obtain spin-related nuclear-nuclear interactions Information and understanding. The self-consistent Skymre HF + RPA model was used to study the GT and SD (spin dipole) transitions of the closed shell nucleus. Tensor interactions have a significant effect on the energy of the main peak of these transitions, The intensity of the quantum interaction gives a very strong constraint. For the pf shell nuclei of N ~ Z, the IS (Isotope Scalar) interaction has a decisive effect on the low-energy GT state. The energies of the low-energy GT states through some specific nuclei Well constrained IS Interaction Intensity.
