简化模型中超流核的库珀对尺寸

Cooper pair sizes in superfluid nuclei in a simplified model

X. Vinas, P. Schuck, N. Pillet

摘要:

库珀对的大小进行了评估,在一个简单的谐振子模型再现复杂的HFB计算值。分析了原子核表面库珀对尺寸很小(2.0-2.5 μ m)的根本原因。结果表明,核体积的约束性质是主要的影响。有人认为,对于库珀对的大小LDA是特别不适应。

英文摘要:

Cooper pair sizes are evaluated in a simple harmonic oscillator model reproducing the values of sophisticated HFB calculations. Underlying reasons for the very small sizes of 2.0-2.5 fm of Cooper pairs in the surface of nuclei are analysed. It is shown that the confining properties of the nuclear volume is the dominating effect. It is argued that for Cooper pair sizes LDA is particularly inadapted.
