摘要：

We show that at high temperatures, the columnar defects generated in YBaCuO crystals by 0.58 GeV Sn-116(30+) have a natural splay of similar to 10 degrees and produce a 10 times larger persistent current density end a 10 times smaller creep rate, than well aligned tracks created by 1.08 GeV Sn-197(23+), with splay of only similar to 2 degrees.
