Abstract

Evidence is presented for the existence of two isomers in $Y^{85}$ with half-lives of 2.9±0.2-h and 4.7±0.2-h. Positron, photon, and x-ray measurements, both singles and coincidence, were performed. No evidence was obtained for the existence of an isomeric transition between the two isomers.
