IIRC it's like a Wilcoxon 2-sample test, except that the ranks are transformed to normal scores. If that's the right test, it has ARE 1 vs the t-test (it has good power for small deviations), but as you move to larger deviations, its power curve flattens out short of 1. Checking the internet: ... 9. Bell, C. B.; Doksum, K. A. Some new distribution-free statistics. Ann. Math. Statist 36 1965 203--214. ... 12. Bell, C. B.; Doksum, K. A. "Optimal" one-sample distribution-free tests and their two-sample extensions. Ann. Math. Statist. 37 1966 120--132. ... it would just about have to be one of these two papers.
