THE NEUTRON-DEFICIENT YTTRIUM ISOTOPES Y$sup 82$, Y$sup 83$, AND Y$sup 8$$sup 4$
Divergences in values of the half life of Y/sup 85/ have been resolved by discovery of a new sup 85/ isomeric state, and the half lives of Y/sup 84/ , Y/sup 83/, and Y/sup 82/ have been evaluated. Powdered arsenic metal targets were bombarded in the Berkeley heavy-ion linear accelerator with carbon ions. Determination by direct decay gives a half life of 39 plus or minus 1 min for Y/ sup 84/. Timed chemical separation values of 9 plus or minus 3 min and 8 plus or minus 2 min were obtained for Y/sup 84/ and Y/sup 83/, respectively. Gamma spectra of Y/sup 84/ and Sr/sup 83/ are shown.
