IDENTIFICATION OF 118AG AS A PRODUCT OF 235U FISSION
Abstract
A search for 118Ag was carried out as part of a study on the distribution of nuclear charge in symmetric fission. A method was developed for the separation of silver from its palladium precursor and cadmium descendant, based upon the rapid reduction and retention of silver by finely divided copper. Silver was separated at various times after thermal-neutron fission of 235U. The copper powder with affixed silver was dissolved in concentrated nitric acid and radiochemically purified for the analysis of 118Cd derived from its silver precursor. The linear relationship between the logarithm of 118Cd activity and separation time led to the identification of 118Ag. The half-life of this radionuclide was determined to be 5.3 +0.9 or -0.7 sec.
