New radioactive isotopes for iridium
Technical Report
·
OSTI ID:402060
The previous work on this element, iridium, has resulted in the observation of a number of radioactive isotopes. However, on the neutron deficient side of the stable isotopes only one period has been reported. The isotope chart shows that the mass numbers of Ir, 186, 187, 188, 189 and 190 can be produced by (a,n), (a,2n), and (a,3n) reactions on rhenium, which has two stable isotopes, Re-185 and Re-187 of relative abundance 38.2% and 61.8% respectively. Using the 60-inch cyclotron at the Crocker Laboratory, this attractive field was investigated. Enriched rhenium isotopes and spongy osmium were also used in confirmatory work concerning the reactions and the mass assignments of the products.
