Δ<r2>(158-156)=0.235 and Δ<r2>(156-154)=0.274 (values are from differences of values reported in 1994Ma57, but based on isotope shift data from 1989Sp04). Uncertainties propagated from data in 1994Ma57 are ≈0.06, but the unstated correlation terms would reduce these uncertainties by a large factor. The same Δ<r2> data are given in plot form in 1990Sp05 and 1991Ho27. Others: Δ<r2>(158-156)≈0.23 fm2 (1987NeZW, obtained from graph by evaluator) and related |l values in the compilation by 1987Au06 and references therein.
