双质子-双中子关联的结构效应

Structure effects of the two protons - two neutrons correlations

M. Grigorescu

摘要:

在玻色子近似下,研究了超流核中质子-中子2粒子- 2空穴的关联,用有效的Josephson型相互作用~[(P+N-)+(P-N+)]描述。这种相互作用的强度估计使用的对称性能量的一个偶数-偶数系统的核子躺在同一个简并的水平。明确地得到了RPA真空,并简要地讨论了质子-中子超流体振荡对交换的等矢量线态的电激发。

英文摘要:

The proton-neutron 2 particles - 2 holes correlations in superfluid nuclei, described by an effective, Josephson-type interaction ~[(P+N-)+(P-N+)], are studied within a boson approximation. The strength of this interaction is estimated using the symmetry energy for an even-even system of nucleons lying on the same degenerate level. The RPA vacuum is obtained explicitly, and the electroexcitation to isovector monopole states of oscillatory pair exchange between the proton and neutron superfluids is briefly discussed.
