Quadrupole deformation parameters of the 98Mo nucleus in two first 0+ (ground and excited) states are determined using Coulomb Excitation method. Matrix elements were determined using the GOSIA code and then analysed using the Quadrupole Sum Rules formalism. Shape coexistence in 98Mo manifests in the very different triaxiality of the two 0+ states. The results are compared with previously known data on 72,74,76Ge isotopes where the similar trend of low-lying 0+ states is observed.
