Abstract
The abundance of samarium-152 in the Santa Clara iron meteorite is found to be 108 × 107 atoms per gram. This quantity, if attributed to fission of a superheavy element with atomic number 107 to 109, limits the amount of superheavy elements in the early solar system to 1.7 × 10-5 times the abundance of uranium-238. For element 110, the limit is 3.4 × 10-5
