Low-spin states of neutron-rich 84,86,88Ge isotopes were measured via in-beam γ-ray spectroscopy after nucleon removal on hydrogen at intermediate energies. The exotic radioactive beams are provided by the RIKEN-RIBF. Based on the spectroscopic information first level schemes of 86,88Ge are derived. The behavior of the 21+, 41+, 22+ level energies and the R4/2 ratio were obtained up to N=56. The data are compared to state of the art shell model and beyond-mean-flied calculations. Triaxial deformation in 86Ge is discussed on the grounds of experimental observations and theoretical predictions.
