The authors apologize for the error in the following information published for this article.
To have a dimensionless δ parameter (Table I and Fig. 4) in our calculations, we used not just the thermal expansion coefficient (αl) but the slope of the liquid metal’s curve, which is αl * ρl = dρl/dT, instead of αl; that is, the following formulas in p. 1381 must be:
and
In Table I, the αl value actually means αl ∗ ρl in Mg/m3⋅K. The data are correct while the column caption αl is wrong. It should be αl ∗ ρl (Mg/m3⋅K).
(Symbol ∗ in the formulas denotes multiplication).
