摘要：

Lifetimes of excited states in Zr-98 have been investigated with a beta gamma gamma fast-timing experiment performed at the Lohengrin mass separator at the Institut Laue-Langevin. Five lifetimes of both yrast and off-yrast states have been measured, including the lowest upper limit for tau(2(1)(+)). The results are compared with recent shell-model and interacting-boson-model calculations.
