Description

The neutron-deficient yttrium isotopes Y82, Y83, and Y84 have been produced by irradiations with the Berkeley heavy-ion linear accelerator. Where possible, identifications were made by establishing genetic relationships with known daughter or granddaughter activities. The half-life of Y84 determined by direct decay is 39+-1 min. By a series of timed chemical separations, the following half-lives have been established: Y82, 9+-3 min; Y83, 8+-2 min. No information pertaining to the radiations emitted in the decay of three yttrium isotopes, other than Y84, has been obtained. The gamma-ray spectra of Y84 and Sr83 are shown.
