• To investigate validity of non-scattering of quasi-particles (S=1) at finite temperature, which Narnhofer et al. claimed, we assume asymptotic completeness at zero temperature and consider whether out-going particles are well-defined or not at finite temperature in Fock space of in-coming particles. It is found in nonlinear Schrodinger model that contrary to the anticipation of Narnhofer et al., not only one particle operator but also continuous background operator contribute to construct in-coming and out-going particles, which are not identical. However Fock spaces of them become inequivalent so that non-scattering of quasi-particles at finite temperature remains not to be denied. It is also noted that LSZ reduction formula for S-matrix does not apply at finite temperature.
