However, helium is unusual in that its isotopic abundance varies greatly depending on its origin.

It is an average over isotopic masses weighted by natural abundance.

Helium, however, is unusual in that its isotopic abundance varies greatly depending on its origin.

Project title: "New methods in nuclear magnetic resonance for the structural analysis of functional materials at natural isotopic abundance" (M/W)

isotopic abundance measurement by gamma spectrometry

During the formation of the embryo skeletons, oxygen from the egg fluids was transferred to the embryo bones, the isotopic abundance of which would depend on the temperature of the egg.

The weighted average of mass of isotopes of the element can be calculated by

The 19F nucleus has a high gyromagnetic ratio (40 MHz/T) and a natural isotopic abundance ratio of 100%.

The precision of the isotope abundances and atomic mass is limited through variations.
