Ytterbium has seven stable isotopes: 168 Yb, 170 Yb, 171 Yb, 172 Yb, 173 Yb, 174 Yb and 176 Yb. It has twenty seven radioisotopes in which the most stable one is 169 Yb have half-life of 32 days. 175 Yb with the half-life of 4.18 days. 166 Yb have 56.7 hours. All remaining have half-lives less than two hours and some have less than 20 minutes. Ytterbium isotopes atomic weight range from 148 Yb.
Ytterbium definition, a rare metallic element found in gadolinite and forming compounds resembling those of yttrium. Symbol: Yb; atomic weight: 173.04; atomic number.
Papers by Keyword: Ytterbium Sesquisulfide. Paper Title Page. Synthesis of Ytterbium Sulfides by the Sulfurization and Heat Treatment. Authors: Liang Li, Shinji Hirai, Hai Bin Yuan, Eiji Nakamura Abstract: Single-phase ytterbium sulfides (Yb 2 S 3 and YbS) were synthesized by sulfurization of Yb 2 O 3 with CS 2 gas and heat treatments. Four kinds of Yb 2 O 3 powders with different particle.
The following uses for ytterbium are gathered from a number of sources as well as from anecdotal comments. I would be delighted to receive corrections as well as additional referenced uses. possible use in improving the grain refinement, strength, and other mechanical properties of stainless steel; one isotope apparently used as a radiation source as a substitute for a portable X-ray machine.
YTTERBIUM FLUORIDE YbF 3 Applications. Ytterbium fluoride, YbF 3, is a low-index film material that exhibits good transparency from the UV through far-infrared regions.The films are insoluble and show low stress, making YbF 3 a useful substitute for ThF 4 in many IR applications. It can be combined in multi-layers with higher-index ZnS, ZnSe and Ge layers and with other fluoride compounds.
Ytterbium. An element of the rare earth family of metals. It has the atomic symbol Yb, atomic number 70, and atomic weight 173. Ytterbium has been used in lasers and as a portable x-ray source.

Monazite is often 50% rare earth by weight and typically 0.03% ytterbium. Atomic Symbol Yb Uses.
Collisional Perturbation of States in Atomic Ytterbium 7 Although the symmetry of physical systems with respect to mirror reflection appears intuitive, in 1956 Lee and Yang -- motivated by the experimental observation of two nearly identical particles which differed only in the parity of their decay products --.
The 6s2 1S0 ( 6s5d 3D1 transition in atomic ytterbium (Yb) was recently proposed as a candidate for the study of parity nonconservation (PNC) (1) (hereafter the upper and lower states of this transition will be referred to as 1S0 and 3D1, respectively). This transition is well suited for the PNC-Stark interference technique, with a relatively large predicted PNC-induced E1 amplitude ( ( 10-9.
