Because the relative abundances of the potassium isotopes are known, the 39 Ar K (produced from 39 K by a fast neutron reaction) can be used as a proxy for potassium. Therefore, unlike the conventional K/Ar technique, absolute abundances need not be measured. Instead, the ratios of the different argon isotopes are measured, yielding more precise and accurate results. Additional advantages of the single isotopic measurements of the 40 Ar/ 39 Ar technique are decreased effects of sample inhomogeneity and the use of smaller sample sizes.
