Here, excited states of 89Zr and 91Mo have been investigated using the fusion reaction 6Li+89Y at beam energy of 34 MeV. Based on new experimental data, about 16 (13) new transitions have been added to the level scheme of 89Zr (91Mo). The level structures are investigated in the framework of the spherical-basis shell model using the effective interactions JUN45 and GWBXG. Reasonable agreement is obtained between the experimental results and the calculations. The calculated results indicate the newly proposed states are characterized by proton excitations from the 1f5/2, 2p3/2, 2p1/2 orbits to the high-j 1g9/2 orbit. The systematic features of low lying states in the N = 49 isotones are discussed.
