标题： Magnetic excitations in nuclei with neutron excess

摘要： $1^+$、$2^-$和$3^+$模式的激发在$^{16}$O、$^{22}$O、$^{24}$O、$^{28}$O、$^{40}$Ca、$^{48}$Ca、$^{52}$Ca 和$^{60}$Ca 核中通过自洽随机相位近似计算进行研究。 包含张量-同位旋项的Gogny型短程相互作用被使用。 我们分析了磁共振随着中子数增加的演化，集体效应的相关性，连续谱正确处理的必要性以及张量力的作用。 显示英文摘要

摘要： The excitation of the $1^+$, $2^-$ and $3^+$ modes in $^{16}$O, $^{22}$O, $^{24}$O, $^{28}$O, $^{40}$Ca, $^{48}$Ca, $^{52}$Ca and $^{60}$Ca nuclei is studied with self-consistent random phase approximation calculations. Finite-range interactions of Gogny type, containing also tensor-isospin terms, are used. We analyze the evolution of the magnetic resonances with the increasing number of neutrons, the relevance of collective effects, the need of a correct treatment of the continuum and the role of the tensor force.
