The isotopic composition of Sm has been measured in the Allende inclusions C1 and EK1-4-1. These inclusions were previously shown to have isotopic anomalies for the elements O, Mg, Ca, Ba and Nd. Sample C1 has a normal Sm isotopic composition except for the ''p-process'' isotope 144Sm, which has an excess of 15¿5 parts in 104. Sample EK1-4-1 was found to have Sm with a highly aberrant composition, indicating excess at all unshielded isotopes and an excess at 144Sm. These data confirm the previous evidence for an additon of ''r-process'' isotopes to this material and also indicate an addition to the ''p-process'' isotope 144Sm. From the observations on C1 it is inferred that the ''p-process,'' addition is decoupled from the ''r-process'' addition. |
