Double beta decay of U-238
Description
During the last period, two samples of 33 yr old uranyl nitrate have been examined for the accumulation of Pu-238 formed as a result of double beta decay. The 2.5 kg sample has led only to an upper limit of 6 x 1020 yr. The 8.5 kg sample has produced positive results corresponding to a half-life of 2 x 1021 yr. The possibility of contaminating nuclear reactions has been carefully examined and eliminated. The possibility that contamination may have been introduced by the large quantities of chemicals that were used is being investigated. 5 refs
