Excitation functions, neutron spectra, and angular distributions in the (p,n) reaction on isotopes of 56Fe, 57Fe, 90Zr, and 94Zr have been measured in the proton energy range of (7-11) MeV. The measurements were performed on the pulsed tandem accelerator EGP-15 of IPPE by time-of-flight fast neutron spectrometer. Analyses of the measured data have been carried out in the framework of statistical equilibrium and pre-equilibrium models of nuclear reactions. The contribution of non-equilibrium emission has been studied. The nuclear level densities of 56Co, 57Co 90Nb, 94Nb, and their energy dependences have been determined.
