All-angle behavior of nucleon-nucleon elastic scattering is examined in terms of factorizable urbaryon rearrangement amplitudes. The regions relevant to Regge-like form, scaling form s^<-N>f (cos θ) and transitional form of the all-angle amplitudes are found from detailed study of angular distribution, effective Regge trajectory, effective exponent N and exp(-s・sin θ/const) behavior of dσ/dt. The Regge-like form has only the restricted range [numerical formula] of application. It is also found that the existing data (p_L&lism;25 GeV/c) comes nearer to the scaling form but do not reach it. In the all-angle amplitudes, the scaling could be attained in the energy region p_L≳50 GeV/c at large momentum transfer. The correspondence of the respective forms of the urbaryon rearrangement amplitudes to the experimental data gives evidence in support of the factorizable structure of the amplitudes.
