The passage around this formula

…to the transition used in strontium-lattice-clock proposals for this kind of experiment [ 11 , 13 ] , giving $\Delta$ $\nu$ $\approx$ 4.295 $\times$ 10^{14}\, $\mathrm{Hz}$ and $\Delta$ E=h $\Delta$ $\nu$ $\approx$ 2.846 $\times$ 10^{-19}\, $\mathrm J$ , a mass excess $\Delta$ E/ $c^2$ $\approx$ 3.167 $\times$ 10^{-36}\, $\mathrm{kg}$ .
