|Er and Yb nuclides|
|I need either the natural isotope composition (preferably) or all natural occuring isotopes (for Er: mass numbers 162, 164,166,167,168,170; for Yb:168,170,171,172,173,174,176; even the very rare Yb-168 yould be important as it has an extraordinarily strong resonance in my region of interest.|
|Only Er-166, -167 are available as an Evaluated Data file.
You may use Mughabghab compilation (Academic Press, 1984),
there are Er-162, 164, 166, 167, 168, 170 and Yb-168, 169, 170, 171, 172, 173,
