abstract
We have investigated the nonlinear features of the propagation of zero sound pulses near a collective mode attenuation peak in 3HeB. These include an amplitude dependence of the attenuation, group velocity and pulse shape. We suggest, that above a threshold excitation level the sound pulse propagates as a soliton. 1981.
