N2 - The (n, 2n) reaction cross section was measured for 93Nb, 197Au and 238U with fission-neutron spectrum from 252Cf 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 σn,2n = f(N - Z A) is dependent on the incoming neutron energy. The function at fission spectrum is of the shape ex - 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.
