198Hg
198Hg is a stable isotope of the element mercury (Hg) with a mass number of 198. It contains 80 protons, and therefore has 118 neutrons. As an even-even nuclide, its nuclear spin is zero, and it possesses no nuclear magnetic moment.
This isotope is one of seven stable isotopes of mercury that occur naturally: 196Hg, 198Hg, 199Hg, 200Hg,
The natural abundance of 198Hg varies among samples and is determined by isotopic composition measured via
Because it has zero nuclear spin, 198Hg does not participate in hyperfine interactions, which has implications
