• A precise measurement on the cylindrical ion acoustic soliton is performed in a coaxial DP-type plasma devise. The experimental results of the velocity variation on the amplitude, and on the radial position are in good agreement with the numerical simulation based on the modified Boussinesq or the K-dV equations. The spatial width of a soliton pulse is wider than the predicted value and shows the larger value than the one-dimensional case. The scattering of solitons is observed after the collapse of cylindrical ion acoustic soliton at the plasma center. This is discussed as the resonance type scattering, and the conservations of energy and momentum are confirmed. The multiple soliton formation is observed before the collapse are in good agreement with the theoretical prediction.
