Kr83m

Kr83m is a rare radioactive isotope of krypton. Krypton itself is a noble gas with the chemical symbol Kr and atomic number 36. Naturally occurring krypton consists of six stable isotopes. Kr83m is a metastable isomer, meaning it exists in an excited nuclear state for a measurable period before decaying to a lower energy state, typically Kr83. This decay often involves the emission of gamma rays.

The existence of Kr83m is primarily of interest in nuclear physics and radiochemistry. It can be produced through various nuclear reactions, often as a byproduct in nuclear reactors or during specific experimental processes. Its relatively short half-life means it is not a significant environmental contaminant in the long term. Applications for Kr83m are limited, but its decay properties can be utilized in certain scientific measurements and research contexts. The "m" in Kr83m denotes its metastable state. Understanding the properties of such isotopes contributes to the broader knowledge of nuclear structure and decay processes.
