Abstract
The scattering vector q resolution of neutron scattering is discussed and the resolution curves in constant wavelength(CW) and time of flight(TOF) mode are given,based on the widely used the angel resolution,beam divergence and the wavelength resolution.The advantages and disadvantages between the two modes are compared.It shows that the resolution of TOF is better for low q range(0.4nm~(-1)) scattering experiment,and that of CW mode is better for high q range,contrastively.
