求Computational problems associated with Racah algebra

Stein J最大公约数算法最初于1967年发表在Journal of Computational Physics,原文标题为：Computational problems associated with Racah algebra，目前版权在Elsevier（http://www.sciencedirect.com/ ），只可惜学校好像没买到这麽老的索引，所以只能查看摘要，要全文需要30刀。。

摘要如下：

Abstract

IN a program written by the author, for performing various calculations in the Racah algebra, some new calculational methods were used; these methods are described in this paper. They include: (1) a representation of numbers alternative to the Rotenberg form; (2) a new algorithm for calculating the greatest common devisor of two odd integers, which was developed for reducing the calculating time in the new representation; (3) methods for shortening the computation time of 3-j and 6-j symbols.

 

不知道哪位同学如果所在学校购买Elsevier的索引足够多，可以帮忙下一下，一饱眼福。
