Isotopes of cerium

{{Short description|none}} {{Infobox cerium isotopes}} Naturally occurring cerium (₅₈Ce) is composed of 4 stable isotopes: ¹³⁶Ce, ¹³⁸Ce, ¹⁴⁰Ce, and ¹⁴²Ce, with ¹⁴⁰Ce being the most abundant (88.45% natural abundance) and the only one that is theoretically stable. The others, ¹³⁶Ce, ¹³⁸Ce, and ¹⁴²Ce are predicted to undergo double beta decay, which has never been observed. There are 35 radioisotopes that have been characterized, with the most stable being ¹⁴⁴Ce, with a half-life of 284.89 days; ¹³⁹Ce, with a half-life of 137.64 days and ¹⁴¹Ce, with a half-life of 32.505 days. All of the remaining radioactive isotopes have half-lives that are less than 4 days and the majority of these have half-lives that are less than 10 minutes.

The known isotopes of cerium range from ¹²¹Ce to ¹⁵⁷Ce, in addition to 14 meta states.
