我们根据文献中的实验观测和已知的远程色散系数值确定了{sup 87}红细胞的a {sup 3}{sigma}{sup +}电位的散射长度。我们的分析使用量子缺陷理论和范德瓦尔斯势的薛定谔方程的解析解。我们发现散射长度为700{sub -300}{sup +700}a{sub 0}或（176{+-}2）a{sub 0}与第一个值相关，其中a{sub 0}=0.052 92 nm为玻尔半径。无法确定范德华系数的独立值，采用理论上确定的最佳C{sub 6}值。
We have determined the scattering length of the a {sup 3}{sigma}{sup +} potential of {sup 87}RbCs based on experimental observations from the literature and the known value for the long-range dispersion coefficient. Our analysis uses quantum defect theory and analytical solutions of the Schroedinger equation for a van der Waals potential. We find that the scattering length is either 700{sub -300}{sup +700}a{sub 0} or (176{+-}2)a{sub 0} with more confidence associated with the first value, where a{sub 0}=0.052 92 nm is the Bohr radius. An independent value of the van der Waals coefficient could not be determined and the best theoretically determined C{sub 6} value was used.
