On April 24, 2008, a group led by Amnon Marinov at the Hebrew University of Jerusalem claimed to have found single atoms of 122 in naturally occurring thorium deposits at an abundance of between 10 and 10 relative to thorium. The claim of Marinov et al. was criticized by a part of the scientific community. Marinov claimed that he had submitted the article to the journals Nature and Nature Physics but both turned it down without sending it for peer review. The 122 atoms were claimed to be superdeformed or hyperdeformed isomers, with a half-life of at least 100 million years.
