Abstract: The h-index-defined as the value such that an individual has
published at least h papers with at least h citations-has become a popular
metric for assessing the citation impact of scientists. As already noted in the
original work of Hirsch and as evidenced from data for a representative sample
of 255 physicists, root c scales as h, where c is the total number of citations
for an individual. Thus root c appears to be equivalent to the h-index. As a
further check of this equivalence, the distribution of the ratio s equivalent to
root c/2h for this sample is sharply peaked about 1. The outliers in this
distribution reveal fundamentally different kinds of individual publication records.
