Ytterbium-175 is a radioactive isotope of the chemical element ytterbium, which, in addition to the element-specific 70 protons, has 105 neutrons in the atomic nucleus; this results in the mass number 175. The very short-lived, only artificially producible, unstable and therefore radioactive nuclide 175Yb can be generated by neutron capture from Ytterbium-174.
174Yb(n, γ)175Yb → 175Lu (stable); σ= 69 Barn.
The decay properties of the Radiolanthanide could be of interest for medical applications.

The half-life of ytterbium-175 was redetermined in 2021 [1]: It is therefore 4.1615(30) days (= 3.595536 × 10 5 seconds); this corresponds to a relative deviation of 0.56% from the above value (ENSDF 2004).
Half-life T½ = 4.185(1) d respectively 361584 × 105 seconds s.
