Neutron coherent scattering study at the structural phase transition point of KDCO3 crystalhas been carried out. Strong quasielastic diffuse scattering is observed. From the detailed analysisof the intensity distribution in a wide range of' the reciprocal space, we conclude as follows: (i)Even at T >T., the individual dimer is already defornaed by the self-trapping of deuterons, thuslocally breaking the synametry of the averaged lattice within the tirne interval determined by theenergy resolution limit of the spectronaeter (T< 0.8 x 10 " sec). (ii) The inter-dimer interactiontakes place via the strain field indtrced by the deformed dimers in the self-trapped state. (111)The structural phase transition is triggered mainly by the strain-mediated indirect interactionbetween the dimers.
