Enriched stable isotopes of gadolinium (Gd, Z = 64): 7 isotopes with enrichment up to 98.40 at.% (¹⁶⁰Gd). Chemical form: oxide. Packaging from milligrams; every lot comes with a passport stating its isotopic and chemical composition.
| Isotope | Enrichment, at.% | |
|---|---|---|
| ¹⁵²Gd | 37.30 | |
| ¹⁵⁴Gd | 67.90 | |
| ¹⁵⁵Gd | 92.20 | |
| ¹⁵⁶Gd | 96.20 | |
| ¹⁵⁷Gd | 91.00 | |
| ¹⁵⁸Gd | 97.60 | |
| ¹⁶⁰Gd | 98.40 |
Enrichment is the atomic fraction of the target isotope, %. Data are given according to the producer’s specification; the exact composition of a lot is stated in its passport. Availability, packaging and price on request. Export of isotope products is subject to export control requirements.
