77-coincidence and angular correlation measurements were performed for transitions in 98gr and 98Zr at the on-line-separator facility OSTIS at the Institute Laue-Langevin (ILL) in Grenoble, France. These nuclei were populated by /3-decay from isotopically pure 98Rb produced by thermal fission of 235U. 7y-angular correlations were measured allowing spin assignments for most levels up to 2 MeV in both nuclei. Listings of angular correlation coefficients and multipole mixing ratios are given. The appearance of shape coexistence is discussed for 98St and 98Zr in the framework of level systematics as well as neutron-separation energies.
