## Abstract

The (n, 2n) reaction cross section was measured for ^{93}Nb, ^{197}Au and ^{238}U with fission-neutron spectrum from ^{252}Cf sources. The cross-section dependence on the asymmetry term N - Z A (where N, Z and A are the nucleus neutron, proton and mass numbers) was investigated and found to be an exponential growth. The mathematical function describing σ_{n,2n} = f(N - Z A) is dependent on the incoming neutron energy. The function at fission spectrum is of the shape e^{x} - 1 while at 14-15 MeV it has the shape of 1 - e^{-x} (where x stands for N - Z A). Looking for an analogy between the asymmetry term dependence and energy dependence, a similar change occurs in the energy-dependent cross section near threshold.
