0+2 bands in 98Sr and 100Zr, populated in spontaneous fission of 248Cm and 252Cf, have been studied using the Eurogam2 and Gammasphere arrays. Phenomenological classification of excited 0+ levels in even-even nuclei of the A ≈ 100 region into four categories is presented and an interpretation for each category is proposed. Highly deformed 0+1 ground states and low-energy 0+2 levels in both nuclei are probably due to the 2p-2h excitation of two neutrons from the 9/2+[404] extruder to the low-Ω prolate and the 11/2[505] oblate orbitals originating from the h11/2 shell, respectively. As a result, candidates for 0+, β vibrational states in A ≈ 100 region are suggested at N > 60.
