Abstract Study of theβ-decay of98Y and of the level scheme of98Zr was undertaken by the use of the two recoil fission product separators JOSEF and LOHENGRIN. Twoβ-decay modes have been detected for98Y, the half-lives of which are 0.65±0.05 s and 2.0±0.2 s. The spins and parities of the two states which undergoβ-decay are proposed to be 1+ and 4−, respectively, with the configurations (π1g 9/2)(ν1g 7/2) and (π2p 1/2 (ν1g 7/2). The measuredQ β -value is 7300±400 keV for the 0.65 s decay. The level scheme of98Zr was deduced fromγ,γ-coincidence data. Absoluteγ-intensities were obtained from two independent measurements. The half-life of the first excited state of98Zr at 853.0 keV with spin and parity 0+ was determined through delayedγ, e−-measurements to be 63 ±7ns. No indication of the coexistence of two different nuclear shapes of98Zr was found.
