N2 - 32S and12C induced compound reactions on Fe, Ni and Se targets have been used to produce neutron deficient nuclei in the mass region 84≦A ≦87. In-beam γ-ray spectroscopy consisting of the measurement of excitation functions, γγ coincidences and γ-ray angular distributions has been performed. The following level energies and spin-parity values have been deduced:84Zr: 540 keV, 2+; 1262.8, (4+); 2137.2, (6+); 3089.286Zr: 751.9, 2+; 1666.6, (4+); 2670.0, (6+); 2705.5, (5); 3271.3; 3298.5, (8+); 3423.5, (7); 3531.5, (10+); 3645.9; 4326.1; 4417.3 Half-lives and energies of γ-rays from the residual activities have been measured. The existence of three new isotopes could be established by their radioactive decay:84Nb(12±3 s)→84Zr86Nb(80±12 s)→86Zr87Mo(14.6±1.5 s)→87Nb→87Zr
