Zn67

Zn-67, or zinc-67, is a stable isotope of zinc with a mass number of 67. It is one of the five stable zinc isotopes, the others being Zn-64, Zn-66, Zn-68, and Zn-70. In nature, zinc consists of about 4% Zn-67, with the remainder made up of the other stable isotopes in varying abundances.

Nuclear properties of Zn-67 include Z = 30 and N = 37. It is an odd-odd nucleus, and its ground-state spin is 5/2−. Because it has a non-zero nuclear spin, Zn-67 is NMR-active and exhibits quadrupolar interactions in suitable environments. As a stable nuclide, Zn-67 does not undergo radioactive decay under ordinary conditions.

Natural occurrence and production are tied to its place among zinc isotopes. Zn-67 is found in zinc-containing minerals and alloys as part of the natural isotopic mixture. It can also be produced or enriched for scientific studies through standard isotope separation techniques or nuclear reactions in laboratory settings, depending on the application.

Applications and relevance of Zn-67 are mainly in scientific research. Its non-zero spin makes it useful for nuclear magnetic resonance studies of zinc-containing compounds and in various isotopic analysis or tracer experiments. Isotopic composition measurements involving Zn-67 are performed in geochemical, environmental, and materials research to understand zinc metabolism, cycling, and industrial processes.
