[en] Data on measuring the spectra of neutron emission from ⁹³Nb nuclei and (n, 2n) reaction cross sections are presented. Measurements were conducted by the time-of-flight method at 14MeV initial neutron energy. Spectra of neutrons scattered at 30, 45, 60, 75, 90, 105, 120 and 135 deg angles were measured. The primary neutron spectrum was calculated and then subtracted from the experimental total spectrum in order to obtain the secondary neutron spectrum. Calculations were conducted in two versions according to SMT-80 and STAPRE programs. The obtained values of the (n, 2n) reaction cross section differ slightly and equal 1347-1375 mb. It is concluded that the values obtained agree satisfactorily with those calculated earlier
